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 ∇×(∇×E)=(ω/c2E] is computed in real space. The plasma impedance matrix is calculated separately, e.g., analytically or from a full‐wave code such as ORION.
