Sažetak
The analysis of electromagnetic field coupling to multiple wires buried in a lossy half-space is of interest in many electromagnetic compatibility (EMC) applications (communications and power cables, geophysical investigations, etc.) and can be carried out by using the thin wire antenna theory, or transmission line model in the frequency and time domain. In this work both antenna theory and transmission line approach in the frequency domain has been used to study frequency behaviour of multiple buried wires. The formulation arising from the wire antenna theory in the frequency domain is based on the set of coupled Pocklington integro-differential equations for half-space problems. The frequency domain transmission line model is based on the corresponding Telegrapher's equations [1], [3]. The frequency domain coupled integro-differential equations frequency domain, arising from the wire antenna theory are numerically handled via the frequency and time domain Galerkin-Bubnov scheme of the Indirect Boundary Element Method (GB-IBEM). The frequency domain transmission line equations are treated using chain matrix method.
