Abstract

Scattering of the Gaussian video pulse by a perfectly conducting circular cone coated with dielectric is considered. The problem is solved using the method of integral equations in the low and resonance frequency bands followed by applying the Fourier transform to obtain time-domain responses. Backscattered fields are investigated for different permittivities of the dielectric in the case of the axial incidence of a plane wave.
