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 reflections at the sample‐air interface is avoided and higher power‐absorption rates within the sample and high‐efficiency designs are obtained. © 2004 Wiley Periodicals, Inc.
