%X In this paper, a novel load-matching procedure for
microwave-heating applicators is presented and tested. In order to
accomplish the optimization procedure, an optimization method
based on the use of the Lebenverg–Marquardt technique has
been specifically developed and tested on two different microwave
ovens. The proposed procedure allows an efficient optimization of
three-dimensional microwave applicators by means of the dielectric
sample relocation as a function of its complex permittivity,
size, and operating frequency. Experimental measurements of
the reflection coefficient are presented and analyzed over several
samples and multimode cavities. Results indicate that high power
efficiencies can be obtained provided that operating frequency
is not just below TM-mode cutoff frequencies for the transverse
dimensions of the oven.
