Abstract
AbstractExtension and application of the NEC (numerical electromagnetics code) thin‐wire model to a wire dipole in an infinite chiral medium and vertically oriented near an interface between a free space and a chiral half space is described. This particular problem was chosen as one in a sequence leading to a capability for modeling wire antennas and scatterers of arbitrary geometry located on either side of, or penetrating such an interface. Results are presented as a function of medium chirality for the dipole in an infinite medium and as a function of chirality and height for the half‐space problem. An approximation for the latter problem which uses the reflection‐coefficient approximation (RCA) is compared with the rigorous treatment and found to produce acceptable results for the cases studied.
