Pulsed EM Field Coupling Between Two Narrow Strips on a Dielectric Half-Space: A One-Segment Solution Based on the Cagniard-DeHoop Method of Moments

Abstract

The time-domain (TD) electric current induced on two coupled, narrow thin strips located on a dielectric half-space is analyzed with the aid of the Cagniard-DeHoop method of moments (CdH-MoM). The problem is formulated using the complex-frequency domain EM reciprocity theorem that is cast into the matrix form whose entries are expressed via a wave slowness representation. The system of equations is then transformed to the TD analytically, which yields a convolution-type system of equations that is solved for TD induced currents via the marching-on-in-time technique.
