Abstract :
The new method of measuring permittivity is described. The measurements are performed using whispering gallery mode open dielectric resonators. The accuracy is assured by applications of the mode matching method. Three resonant modes (HE511, HE611 and HE 711) are used in the measurement procedure. The accuracy of the method is much better than 0.3% for the relative permittivity having values from 20 to 50
