Analysis on Aperture Size for Electromagnetic Scattering by Circular Strips with Impedance Boundary Conditions

Abstract

This study investigates how altering the aperture size and impedance characteristics of a circular strip, when excited by a cylindrical wave, influences electromagnetic scattering. The focus is on understanding the impact of shifting the position of an H-polarized line source and adjusting parameters such as strip aperture, wave number, and impedance values on the overall behavior of the electromagnetic field. Our findings reveal that changes in the strip's aperture dimensions or wave number, even when regarding the latter's relation to the source, lead to significant alterations in the surrounding electromagnetic field. This scrutiny unveils a detailed interplay between these factors within this electromagnetic scenario. By examining these intricacies, our study sheds light on the substantial impact of subtle modifications in the strip's dimensions, combined with adjustments in wave and source characteristics, on the electromagnetic field. This understanding holds promise for advancements in diverse engineering applications.
