ANALYSIS OF MICROWAVE CAVITY LOADED WITH LOSSY DIELECTRIC SLAB BY MEANS OF MODE MATCHING METHOD AND OPTIMIZATION OF LOAD LOCATION

OpenAlex İngilizce

An analysis is presented by means of a mode matching method for two microwave cavities of difierent sizes which are fed by a TE10 waveguide and loaded with lossy dielectric slab type material. The accuracy of the results obtained is presented together with a comparison of the results which are obtained by the HFSS numerical method. Optimization of the load location was performed in order to maximize the electrical fleld on the material. The principle of this optimization is based on flnding the existence of the positions in which the re∞ection coe-cient S11 is the lowest. When the feeding guide for the two difierent microwave cavities was at the centre of the resonator, the change in the re∞ection coe-cient distribution was detected according to the difierent positions of the material in the oven, and then the lowest positions were found. The changes in the electric fleld in the detected positions were recorded.
