Whispering gallery resonator method for permittivity measurements

Description

This item was taken from the IEEE Conference ' Whispering gallery resonator method for permittivity measurements ' 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 (HE/sub 511/, HE/sub 611/ and HE/sub 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.
