Abstract : The serious effect of air gaps on the measurement of high dielectric- constant values is discussed. Two measurement techniques are described in which air gaps are made to be insignificant sources of error. The parameters affecting coupling between dielectric resonators are explained. Two pairs of dielectric resonators and three different sizes of waveguides were used to obtain six sets of coupling-coefficient data. The measured values are compared to curves computed from the coupling-coefficient formula. In the range of validity of the coupling formula, the accuracy is adequate for ordinary design purposes.
