Fullwave coupling to a 3D antenna code using Green's function formulation of wave-particle response

Using the fullwave code, TORIC, and the 3D antenna code, TOPICA, we construct a complete linear system for the RF driven plasma. The 3D finite element antenna code, TOPICA, requires an admittance, \textbf{Y}, for the plasma, where $B=\mathbf{Y}\bullet E$. In this work, TORIC was modified to allow excitation of the ($E_\eta $, $E_\zeta)$ electric field components at the plasma surface, corresponding to a single poloidal and toroidal mode number combination (m,n). This leads to the tensor response: $\mathbf{Y_n}= \left( \begin{array}{ll} Y_{\eta \eta } & Y_{\eta \zeta} \\ Y_{\zeta \eta } & Y_{\zeta \zeta } \end{array}\right)$, where each of the $\mathbf{Y}_n$ submatrices is $N_m$ in size. It is shown that the admittance matrix is equivalent to a Green's function calculation for the fullwave system and the net work done is less than twice a single fullwave calculation. The admittance calculation is used with loading calculation from TOPICA to construct self consistent plasma and antenna currents.
