Losses in an open microwave resonator with an ultrathin cylinder

Two methods are used to calculate the losses introduced in an open resonator by an ultrathin cylindrical sample placed in the antinode of the electric field of the main oscillation mode. It is demonstrated that the dependence of the losses on the cylinder parameters for wires is ambiguous in charact...

Description
Summary:Two methods are used to calculate the losses introduced in an open resonator by an ultrathin cylindrical sample placed in the antinode of the electric field of the main oscillation mode. It is demonstrated that the dependence of the losses on the cylinder parameters for wires is ambiguous in character, which must be considered when developing methods for measuring and control of characteristics of such objects placed in open quasioptical resonators. In special cases, some parameters of the examined samples can be determined only from measurements of the losses introduced in the open resonator.
