Summary: 
In this paper, we present a numerical analysis for resonant characteristics of the TM010 mode of a cylindrical cavity containing a dielectric rod and a conductive layer on its metal walls. This analysis uses the mode matching method for calculation. Error in complex permittivity of a loaded dielectric rod measured using a layered cavity is evaluated as a function of thickness and layered conductor conductivity. A thick layered cavity is necessary for precise measurement of material properties using the cavity resonator method at microwave and millimeter-wave frequencies.
