Abstract

This paper presents an accurate formulation and integration scheme for computing vector potential interactions due to linear basis functions in lossy conducting media over wide frequency ranges. The emphasis is on an approach that is broadband and works both at high- frequency surface impedance limits and at low-frequency volumetric current flow limits. The method can be interpreted as a step towards a surface-only formulation for integral-equation based broadband characterization.
