Application of a Cylindrical Resonator for Measuring the Parameters of Dielectric Materials
P. 1–4.
One of the promising areas of microwave
resonator systems application is the possibility of their use as
frequency-selective structures for the control of physical
quantities and monitoring of process parameters. It is possible to
determine parameters of planar dielectric materials – dielectric
permittivity and dielectric loss tangent by measuring
electrodynamic characteristics of a cylinder resonator with H011
mode. Here we present the results of analytical assessment,
computer modeling in Ansoft HFSS v.12 and experimental data.
The measurement error in determining the dielectric parameters
of the material does not exceed a fraction of a percent of the table
values.

Owing to the exceptional mechanical and optical properties of atomically thin
materials, nano-electro-mechanical systems (NEMS) resonators hold great
promise for various sensing applications requiring high resolution and broad
dynamic range (DR). However, these applications are often challenged by
variations in parameters, including temperature, making the preservation of a
stable and large dynamic range across different temperature ranges a big
challenge. Here, ...
