Numerical Treatment for Time Domain Integral Equations of Thin Wire Structures in Half-Space Configuration

For the modeling of electromagnetic scatter of thin metal wires located above or under real ground, a new numerical method based on time domain integral equations is presented. The influence of lossy ground is taken into account via Fresnel space-time reflection coefficient. The integral equations are solved efficiently by method of moments combined with marching on in time procedure. The calculated results agree with those of references. The method is also verified by the experiment in near field.
