## 4 Graphical Results  
Now we shall present graphical illustrations of the diffracted field for different parameters and investigate the trends of diffraction characteristics of the diffracted field. From Figure 2a, we note that the modulus of higher frequency of swinging strip attains the prominent amplitude of the diffracted field compared to the modulus of lower frequency of the swinging strip. Figure 2b portrays that the incidence wave with the higher modulus of frequency will yield an elevated amplitude of the diffracted field which is in accordance with the physics of the problem. Figure 2c,d confirm the fact that as the source and the observer are gradually taken far from the origin, the amplitude of the separated field decreases. Figure 3a illustrates that on increasing the incidence angle, the amplitude of the diffracted field also becomes adulatory. Figure 3a-d given below are in close agreement with Figures 2-6 of [22], respectively. As the strip length is increased gradually from \(l=10^{1}\), \(l=10^{14}\) to \(l=10^{22}\) as depicted in Figures 2 and 3 the trends of the graphs are the same as of the half-plane situation [22]. Furthermore, Equation (56) shows the generalized expression for the separated field. It can be observed that it contains the term Cn for Fourier coefficients. The problem at hand can be extended and analysis can be performed on the expression for varying input signals present in nature based on these Fourier coefficients. Such signals can include unit gate function, ramp function, unit impulse function, complex exponential, sawtooth wave, triangular wave, square wave, sinc function, etc. Furthermore, this type of solution has practical applications in geophysics in the exploration of mineral, analysis of capacitive elements formed due to soldering in electronics, acoustic signals analysis in sound transmission, miniature antenna design for public use, medical imaging such as in ultrasound for disease detection, etc. [31; 32; 33; 34; 35; 36; 37; 38]. The graph Figure 2a matches with Figure 5 of [22] and Figure 3c matches with Figure 4 of [22]. This is sufficient evidence to show that the graphical results of [22] can be obtained from the present analysis. Figures 2b-d and 3a,b,d do not match the other figures of [22] because the parameters considered are different. Those figures can also be obtained if the parameters were matched. The phenomenon of diffraction that takes place in an incident signal from a strip has been studied and it is applicable to many real-world problems. The applications include electronics, acoustic signals, antenna design, medical imaging, geophysics, etc. Some physical and practical applications for the derived relationships are as follows. In [31], discontinuity in a microstrip such as soldering, gaps, etc. in electronic circuits is studied to determine their capacitive effects. The derived field is the addition of two fields generated by two edges of the strip and an interaction filed and plays a vital role in the study of electromagnetic theory of antennas [32]. In [33], analysis of acoustic signals that are diffracted by slits and ribbons has been performed, which can help in medical imaging using ultrasound. The optical activity and diffraction on a plane from a split aperture can take place in many biological materials such as bacteria, seashells, amino acids, an array of sugars, DNA, laurel, turpentine oil, and aqueous solutions of tartaric acids and the study of such materials can help in medical sciences [34]. The transient of seismic wave, which includes diffraction of waves from a solid strip has been analyzed for a geological region in [35]. The study of seismic waves for geological exploration has been studied in [36]. Brain wave patterns using diffraction theory has been studied in [37] for detection of migraines. In [38], diffraction theory has been applied for the detection of liver disease.
