Resumen
We present a new approach for inferring the electric
field distribution inside materials in multimode cavities with mode
stirrers.We calculate the electric field in the dielectric material by
a two-dimensional modeling of a typical multimode microwave applicator
with some mobile metallic sheets. We compare simulated
results with classical approaches, such as Lambert’s law or a constant
electric field distribution. The proposed method allows for a
better understanding of how these structures can be applied for
heating materials when computing the microwave energy absorption
in the dielectric. Finally, we perform experimental tests in a
microwave multimode oven for validating purposes.
