Abstract
This paper describes a computer program DOTIG4, for the study in the time domain, of the interaction of transient electromagnetic pulses (EMP) with arbitrary perfect conducting (PEC) surfaces modelled by planar triangular patches. DOTIG4 is based on the solution of the Time Domain Electric Field Integral Equation (TD‐EFIE) by the method of moments (MoM) using a marching‐on‐in‐time procedure. The code is applied to transient scattering of several structures and to calculate the input impedance of several broadband antennas.
