Analysis and computer simulation is presented for investigating coupling of Ion Cyclotron Range of Frequency (ICRF) waves to tokamak plasmas using phased coil antenna arrays. The model accounts for 3-D antenna and feeder current effects, an antenna cavity which is finite in all three dimensions and warm plasma effects. The antenna radiation resistance and the spectrum of the ICRF power coupled to the plasma are calculated from the model. The effect of the three-dimensional cavity on the parallel wavenumber spectrum of the coupled power is investigated. Emphasis is on coupling of the fast wave but the model includes parallel electric fields for consideration of slow or ion Bernstein mode excitation. The model also permits studying the effects of variations of the angle between the Faraday shield bars and the tokamak axis. Radiation resistance and spectrum results from the model are presented.
