Authors: Gupta Nisha , Singh Mahendra 
Published: July 2007

AbstractA simple method for calculating the resonant characteristics of unilateral fin‐line cavity is presented. The present method, called the space—spectral‐domain method, is found to be superior to several other methods in terms of computer memory and time, and can be easily implemented on any other arbitrarily shaped resonators. The results obtained are compared with the results available in the literature, and are found to be in good agreement. © 1995 John Wiley & Sons. Inc.

On the efficient representation of the electrodynamic green's function using multiresolution wavelet concepts
Authors: Kim Hyeongdong , Ling Hao 
Published: July 2007

AbstractA multiresolution wavelet concept is applied to efficiently represent the electrodynamic Green's function. In the joint spectral‐spatial representation, the multiscale feature of the spectral‐domain Green's function is clearly revealed. Due to this multiscale feature in the spectral domain, a wavelet application in the spectral domain (KDWT) is more appropriate in representing the Green's function than the wavelet transform applied in the space domain (SDWT). We present a multiresolution implementation of the KDWT and show that the KDWT representation results in a sparser moment impedance matrix than the SDWT representation. © 1995 John Wiley & Sons, Inc.

Super‐resolved time‐frequency processing of surface‐wave mechanisms contained in wideband radar ECHO
Authors: Moore J. , Ling H. 
Published: July 2007

AbstractA time‐frequency super‐resolution procedure is presented for processing wideband backscattered data containing dispersive surface‐wave effects. This approach is based on repeatedly applying the ESPRIT method to a sliding window of frequency data. The raw poles returned by ESPRIT produce a more sharply resolved time‐frequency display than that of the short‐time Fourier transform. One inherent limitation of ESPRIT is that it finds a multitude of poles for a single dispersive scattering mechanism. This limitation is overcome by properly combining the raw poles corresponding to each dispersive mechanism. This pole‐combining approach recovers the true frequency behavior of each dispersive mechanism and allows a complete parameter estimation of the data to be performed. © 1995 John Wiley & Sons, Inc.
Higher‐order infinite elements for quasi‐TEM analysis of microwave transmission lines using the finite‐element method
Authors: Pantic‐Tanner Zorica , Mittra Raj 
Published: July 2007

AbstractHigher‐order infinite elements, which are compatible with ordinary finite elements, and which preserve the sparsity of the FEM equations, are derived for the quasi‐TEM analysis of open‐type microwave transmission lines. The shape of the outer boundary can be an arbitrary polygon and can be chosen to conform to the geometry of the transmission line etches. It is shown that the use of the infinite elements with higher‐order approximation of the radiation condition enhances the efficiency of the method as compared to the conventional FEM, by virtue of the reduction in the requirements for the memory and computation time. © 1995 John Wiley & Sons, Inc.

A novel method to determine equivalent circuits for MMIC plastic packages using electromagnetic field simulation
Authors: Uda Hisanori , Sawai Tetsuro , Harada Yasoo 
Published: July 2007

AbstractA novel method was developed to determine equivalent circuits for plastic packages. The method first divides the package shapes into basic shapes including one or two lead pins, and determines the S parameters of each basic shape using an electromagnetic field simulator. Next, the equivalent circuits and parameters of each shape are determined by a successive fitting technique using a microwave circuit simulator, and these are combined to achieve the total equivalent circuit for the package. The results agree well with measured results. © 1995 John Wiley & Sons, Inc.

Authors: Zhou Xingling , Wang Yue , Zhou Siyong 
Published: July 2007

AbstractBased on two isoperimetric inequalities, it is proposed that the capacitance of an insulated convex conductor is a function of the volume, the surface area, and the surface integral of mean curvature. Then the formula in [1] for computing the capacitance of an insulated conductor of arbitrary shape is greatly improved. Examples show excellent agreement with the existing results. © 1995 John Wiley & Sons, Inc.

Authors: Wenyan Yin 
Published: July 2007

AbstractIn this article the normalized co‐ and cross‐polarized radar cross sections (RCSs) of Faraday chiral cylindrical scatterers are studied. Such scatterers include one‐layer Faraday chiral cylinder and cylindrical shells, and an impedance cylinder coated with a one‐layer Faraday chiral medium. Numerical results are presented to show the combined effects of dispersion and damping of different constitutive parameters on the RCS and near‐field distribution of scatterers. It is believed that the present study provides some insight into the physical features of Faraday chiral materials. © 1995 John Wiley & Sons, Inc.

Authors: Zhang D. G. , Yung Edward K. N. , Ding H. Y. 
Published: July 2007

AbstractA new method for analyzing a millimeter‐wave H‐plane waveguide Y‐junction circulator with a partial height ferrite post is presented. Simple formulas are developed for determining the center frequency of the circulator and the length of the ferrite rod. The lowest mode of operation is not unique and is dependent on the length of the ferrite post. Based on the newly derived formulas, several broadband 3‐mm circulators have been designed, assembled, and tested. Good agreement between the analytically obtained performance and experimental results is observed. © 1995 John Wiley & Sons, Inc.

A mixed FEM approach to stress‐constrained topology optimization
Authors: Bruggi M. , Venini P. 
Published: July 2007

AbstractWe present an alternative topology optimization formulation capable of handling the presence of stress constraints in a straightforward fashion. The main idea is to adopt a mixed finite‐element discretization scheme wherein not only displacements (as usual) but also stresses are the variables entering the formulation. By doing so, any stress constraint may be handled within the optimization procedure without resorting to post‐processing operation typical of displacement‐based techniques that may also cause a loss in accuracy in stress computation if no smoothing of the stress is performed. Two dual variational principles of Hellinger–Reissner type are presented in continuous and discrete form that, which included in a rather general topology optimization problem in the presence of stress constraints that is solved by the method of moving asymptotes (Int. J. Numer. Meth. Engng. 1984; 24(3):359–373). Extensive numerical simulations are performed and ongoing extensions outlined, including the optimization of elastoplastic and incompressible media.

Is a cost of quality system for you?
Authors: Corradi Peter R. 
Published: July 2007

AbstractThe costs that an organization incurs in producing a product or service can be likened to an iceberg. Some quality costs and expenditures are obvious—like the tip of the iceberg—but many quality costs and expenditures are hidden away like the 90 percent of the iceberg below the surface. These quality costs are sometimes referred to as the “cost of doing business” when, in reality, they are the costs of doing things wrong: The accounting department can measure the dollars into and out of an operation or an organization, but many activities within the operation consume such resources as money, material, labor, and utilities without a definitive control process.One of the leaders in the practice of gathering and using data to improve products and services is an organization's quality group. Because this group interacts with all other departments in the organization to assure quality, it has the unique ability to guide the organization toward the use of the “cost of quality” system to help it optimize profits while meeting its obligations to the communities in which it operates. Developed with the assistance of the controller group, this system can be used to identify costs that affect the quality of the products and services that the organization provides, thus improving the quality and profitability of the organization.

The role of nonverbal communications in quality improvement
Authors: Martin Stephanie 
Published: July 2007

AbstractFrom the time you were born you recognized nonverbal communications, even before you learned to speak. The pleasant tone of a voice or the smile on mother's face meant your world was okay. Nonverbal language is such apart of our everyday communications that we seldom take notice of it. But it is in our long‐term business interest to do so. Within the next ten years, over 90 percent of all firms will be adopting practices such as people empowerment, focus teams, and flattened organizations. Effective communication is the key to making these processes work. As leaders in these present and future organizations, we must develop all our communication skills.

Navigating organizational waters with hoshin planning
Authors: Bechtell Michele L. 
Published: July 2007

Abstract“Navigation is the science of determining the position of a ship, aircraft, or guided missile, and charting a course for guiding the craft safely and expeditiously from one point to another,” according to the Encarta Encyclopedia's definition. And so it is with organizations—or, rather, it should be. For the basic yet crucial concepts of navigation are often missing from the corporate lexicon. But with hoshin management—a technique that links daily business activities with strategic objectives—that is changing. A number of world‐class organizations, such as Hewlett‐Packard, Intel, Milliken, Texas Instruments, Zytec, and Procter & Gamble, are using this relatively new management system to steer their organizations toward success.
