Abstract :
A new method for measuring the complex permittivity of a low loss material in the millimeter wave region is developed. The heart of the method is a higher order whispering gallery mode resonator which is made of the material under test. The method has a great advantage for millimeter measurements because the dielectric disk resonator does not need a shielding metal structure. Measured results of some plastic and ceramic materials in the 50 to 110 GHz band are presented
