An approximate computational model of an electromagnetic pulse-excited thin-wire antenna is developed. The presented solution methodology is based on the Cagniard–DeHoop method of moments and Hallén's approximation of the thin-wire model. It is shown that the proposed time-domain solution leads to an inversion-free and efficient updating procedure that mitigates the marching-on-in-time accumulation error. An illustrative numerical example demonstrates the validity of the proposed model.
