Abstract :
Microwave measurements of dielectric loss by a hemispherical open resonator may be in error if the resistivity of the plane mirror on which the sample rests differs greatly from that of the concave mirror. The error can be corrected if the ratio of the two resistivities is known or eliminated by using a sample which is an integral number of half wavelengths long.
