Conformal Array Antenna Design at the Weizmann Institute, Israel . Professor D. Treves, Department of Electronics at the Weizmann Institute of Science, has created a novel laboratory dedicated to the design and testing of conformal, mlcrostrip array antennas. Theoretical models are being developed to predict patterns, bandwidth and losses of the microstrip arrays on curved surfaces. Antennas designed from the theory are then built and tested with a dedicated anechoic chamber. Tests to date show good correlation between theory and test results.

High Speed Calculation of Fourier Coefficients . Further information can be obtained from the undersigned. Theoretical modeling and experimental studies will be conducted and compared to support an on-going applied research effort in boron gas generators as an integral part of ducted rocket development. The particles are then fed at varying velocities into a quartz tube containing gaseous oxidizing atmospheres which simulate either a primary ignition chamber environment or a secondary combustion chamber. Correlations among particle size, temperature, velocity, oxide coating thickness, and oxidizing atmosphere will be made to determine ignition behavior and combustion performance.
