AB - In this paper, several mode-stirrer configurations are
compared in order to establish their influence on the electric-field
uniformity within an irradiated dielectric sample inserted in a microwave-
heating applicator. Two different scenarios are evaluated
with metallic sheets moving inside the multimode applicator. The
different stirrer configurations are tested and compared for low-,
medium-, and high-loss dielectric sample materials. Additionally, a
straightforward procedure based on a generalized plane-wave approach
is proposed and evaluated as a computationally efficient alternative
for calculating the electric-field distribution inside materials
processed in these microwave applicators with mode stirrers.
Although very different electric patterns are achieved depending
on stirrer geometry and sample permittivity, the plane-wave approach
has been shown to provide a very good approximation for
medium and high lossy dielectric materials.
