Matched Asymptotic Expansion for the Low-Frequency Scattering by a Semi-Circular Trough in a Ground Plane

Abstract

Plane wave scattering by an electrically small circular trough cut in an infinite ground plane is solved analytically for both the TM and TE polarizations. A quasi-static solution for the inner field based upon a transformation to bipolar coordinates exploits the failure of the narrow trough to react to the detailed wave nature of the incident field and… (More)
