The modelling of finite-size dielectric (and/or magnetic) material via surface integral equation (SIE) formulations and the method of moments (MoM) in the resonance region is dominated by a triangular-mesh description of the surfaces and supported by Rao–Wilton–Glisson basis functions. Previous formulations allow perfect electric conductor (PEC) thin-wires to be included in the modelling domain when the wires are external or internal to the dielectric surfaces. This study discusses the adjustments to be made in an SIE formulation and MoM to enable the modelling of PEC thin-wires that penetrate one or more dielectric surfaces of finite size and shows that the results are in excellent agreement with the other methods.
