Transient scattering of an L-shaped wire using the singularity expansion method
Abstract
A bent thin wire in the shape of an L is analyzed in free space to determine the transient scattering characteristics by the application of the singularity expansion method (SEM) to a coupled set of Hallen-like equations. The principal results of a parametric study to determine the effect of the bend position on the complex resonant frequencies are reported here. The frequency and the time domain responses are given for several cases of plane wave illumination using the SEM and results are compared to the conventional Fourier transform method.
