abstract = {The response of sapphire WGM resonator to a single-layer
graphene introduced onto the dielectric substrate is studied
in Ka-band. The experimental investigations were performed
for two types of resonator modes: HE and EH. The modes
differ by the prevailing component: electric or magnetic of
electromagnetic field along the resonator longitudinal axis.
The possibility of using these modes for finding graphene
conductivity is demonstrated. Based on the experimental and
the resonator model data obtained using COMSOL Multiphysics
software the graphene conductivity values were obtained. The
conductivity values calculated based on results of
measurements performed on two mode types with different
substrate position relative to the resonator are compared.
The results demonstrate reproducibility. The possible source
of some difference between the results obtained on different
modes is discussed. The recommendations regarding the design
of the most suitable configuration for graphene conductivity
measurements are proposed.},
