On the use of isoparametric elements for BEM modeling of arbitrarily shaped thin wires in electromagnetic compatibility applications

Abstract

The paper deals with the frequency domain Galerkin-Bubnov scheme of the Indirect Boundary Element Method (GB-IBEM) for the solution of the Pocklington integral equations for arbitrary thin wire configurations. The presence of a lossy media is taken into account by using both the reflection coefficient approximation and the rigorous Sommerfeld integral formulation. Some illustrative computational examples related to power line communication systems (PLC) and grounding systems are presented.
