Abstract

Time domain calculation of the transient current distribution along a thin wire antenna array S.

The mathematical model is based on a set of coupled space-time integral equations of the Hallen type. The effect of inhomogeneous medium is taken into account by the space-time reflection coefficient appearing within the integral-equation kernels. Space-time current distributions along the wires are obtained by solving the integral equation set using the time-domain Galerkin- Bubnov Boundary Integral Equation Method (GB-BIEM). Numerical calculation is performed for the three and two wire antenna arrays horizontally located over a dielectric half-space, when the central wire is excited by a time-dependent
