We designed, realized and tested a TE011-mode rectangular, high-permittivity, dielectric resonator, in order to obtain a measuring device capable of applying straight microwave currents to conductive samples. We characterized the prototype by means of extensive simulations that we compared to experimental results. Finally, we tested the device on a strongly anisotropic graphite sample.

Abstract
We designed, realized and tested a TE011-mode rectangular, high-permittivity, dielectric resonator, in order to obtain a measuring device capable of applying straight microwave currents to conductive samples. We characterized the prototype by means of extensive simulations that we compared to experimental results. Finally, we tested the device on a strongly anisotropic graphite sample. We found that the rotation of the sample produced significant changes in the response of the device. We conclude that the proposed rectangular dielectric resonator can be used as a device to detect the anisotropy of conductive samples.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
