Time-Domain Analysis of Thin-Wire Structures Based on the Cagniard-DeHoop Method of Moments

numerically in the time domain (TD) with the aid of the Cagniard-DeHoop method of moments (CdH-MoM). It is demonstrated that the TD solution of such problems can be cast into the form of discrete time-con...
