Abstract

A general method is described for attaching thin wires to surfaces segmented with triangular patches which allows significant versatility in their positioning, whilst maximizing computational efficiency by preserving all of the surface segmentation when wires are added or moved, apart from at the connection patch. Variations on the general methodology of single patch subsegmentation are investigated by introduction of convergence metrics and comparisons with controls for input impedances at the monopole bases.
