Abstract

The analysis of complex grounding systems has been undertaken using the wire antenna model and the set of Pocklington integro-differential equations for curved wires. The corresponding integro-differential realtionships are numerically handled via the Galerkin-Bubnov scheme of the Indirect Boundary Element Method (GB-IBEM). Frequency dependent input impedance is obtained as a ratio of voltage and current at the injection point. The transient response of the structure is computed by using the Invesre Fast Fourier Transform. Some illustrative numerical results for the two-wire junction input and transient impedance.
