Abstract
An electromagnetic exposure chamber was designed to safely deliver
electromagnetic power in the range of microwaves between 0.8 and 4.2 GHz
to a thin cylindrical materials. This instrumentation is unique because
the diagnostics not only measure sample heating with a response time of
1.3 ms, but also energy transmitted and reflected. Energy absorption at
different frequencies was quantified via electromagnetic heating using
an infrared camera. This in situ IR imaging of the spatial distribution
of temperature during microwave exposure coupled with sensors for
determining transmitted and reflected energy enables novel new microwave
energy experiments. Samples were exposed to a portion of both the
electric and magnetic fields inside a waveguide and based on sample
dimensions, the field strengths were assumed uniform across the sample.
Three materials were examined: two were borosilicate, first coated with
graphite paint and a second without the coating; and, the third was a
compressed sa
