Abstract

Thin-wire structures in the presence or absence of a ground plane are analyzed 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-convolution equations. Under the assumption of piecewise linear space-time axial current distribution, the elements of the TD impedance array are derived analytically in terms of elementary functions. Their approximations applying to multi-conductor transmission lines are discussed. Illustrative numerical examples validating the TD solution are presented.
