S. Donovan et al., MICROWAVE CAVITY PERTURBATION TECHNIQUE .2. EXPERIMENTAL SCHEME, International journal of infrared and millimeter waves, 14(12), 1993, pp. 2459-2487
In this paper, the second in a three part series, we describe an exper
imental scheme used to measure the electrodynamical response of a mate
rial in the millimeter wave range of frequency. In particular, with th
is technique we can directly evaluate the complex conductivity from a
measurement of both the bandwidth and characteristic frequency of a re
sonator containing the specimen. We will describe in detail all the te
chnical improvements achieved which provide the required accuracy.
