Computer simulation of microwave radiator on coaxial ribbed line

This paper presents the results of the simulation of a microwave radiator, based on a coaxial ribbed line. This radiator had been designed for physiotherapy treatment of urological diseases. The radiation has a conical in shape rotation symmetry with the declined to the axis vector of the electric field and takes place when the phase velocity in the radiator is less than the light velocity in a treated object (human tissue in the considered case). Software CST Microwave Studio had been used for this simulation.
