Self-consistent 3-D ICRH antenna modeling with plasma

A new solver has been developed for the ARGUS electromagnetic field solver package to analyze the ICRH antenna coupling problem. The key advantages are that complex 3-D structures, e.g., Faraday screen, side walls..., are represented realistically, and that all currents flowing in the structures are solved self-consistently. Plasma response is included as a surface impedance in Fourier-space while the field solution around the antenna [satisfying [del][times]([del][times][bold E])=([omega])/[ital c][sup 2]E] is computed in real space. The plasma impedance matrix is calculated separately, e.g., analytically or from a full-wave code such as ORION.
