A NEW METHOD FOR LOAD MATCHING IN MULTIMODE-MICROWAVE HEATING APPLICATORS BASED ON THE USE OF DIELECTRIC-LAYER SUPERPOSITION

摘要

Usage of a dielectric multilayer around a dielectric sample is studied as a means for improving the efficiency in multimode microwave-heating cavities. The results show that by using additional dielectric constant layers the appearance of undesired re/lections at the sample-air interface is avoided and higher power-absorption rates within the sample and high-efficiency designs are obtained.
