Practical localized waves generation

Since the early works on localized waves (LW), extensive results were published on this important subject, from both the theoretical and the experimental points of view. Nevertheless, those experimental techniques of LW generation suffer from several shortcomings. A major one is that only pulse peaks were accredited. Either the full profile of the generated pulse was not reported, or it was not closely matching the theoretical profile. Additionally, low resolutions of the generated LWs were reported in the acoustic X-Waves. The conductors of the experiment attributed this effect to the limited bandwidth of the excitation elements.The interest in the unique features of LWs and their high potential in different applications were the main motivation for conducting this study. Because of the complex nature of LWs, it is challenging to design a system that can launch LWs with high accuracy and power efficiency as well as the flexibility in choosing the LWs design parameters. Due to practical limitations, the results of this research could not yet be experimentally verified; however, this research aims to provide a practically feasible method for LWs generation that avoids the shortcomings of previous techniques.In the study, the transverse electric (TE) version of the MPS pulse is derived. Expansion in terms of the waveguide's orthogonal modes is presented and followed by the method to determine the excitation currents for the loop antennas inside a circular waveguide. The feasibility and flexibility of the method is demonstrated via numerical examples.
