Abstract

An analytic solution of the wave equation for an inhomogeneous Tokamak plasma is obtained in terms of hypergeometric functions by fitting the Epstein profile, with a maximum of five free parameters, to the dispersion curve. Power radiated from an ICRH antenna is then evaluated by solving a boundary value problem. The radiation resistance and inductance obtained by this method are compared in a particular case, for illustration, with those employing numerical integration and are found to be typically 10% higher. Replacing the numerical integration by the curve fitting procedure in the plasma region, a considerable saving of computer time can be achieved.
