Abstract

The results for the estimation of the effective surface conductivity of the walls of a multimode microwave cavity applicator, based on measurements of reflected power from the cavity, were analyzed. The power reflection coefficient from an overmoded cylindrical applicator cavity as a function of the wall conductivity was found by a method based on the expansion of the total microwave fields in the eigenmodes of the cylindrical waveguides. It is found that a comparison of the average reflectivity over a broad frequency interval containing many cavity resonances combined with a calculation of microwave reflectivity as a function of surface reflectivity. This is the best means of determining the effective conductivity of the walls.
