DOTIG4, a time-domain numerical code for the study of the interaction of electromagnetic pulses with arbitrary conducting surfaces. (English) Zbl 0927.65124
Summary: This paper describes a computer program DOTIG4, for the study in the time domain, of the interaction of transient electromagnetic pulses with arbitrary perfect conducting surfaces modelled by planar triangular patches. DOTIG4 is based on the solution of the time domain electric field integral equation by the method of moments 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.
