Abstract

The conventional cavity perturbation method of placing the sample on the broad wall of a rectangular cavity resonator is altered by placing the sample on a narrow wall of the cavity and an analytical formula is proposed for measuring the dielectric properties of medium loss materials at microwave frequencies. Advantages and limitations of the analytical technique over earlier approaches of calibration techniques are also presented..
