Microwave Properties of Yttrium Vanadate Crystals at Cryogenic Temperatures
Abstract
Yttrium Vanadate is a birefringent crystal material used in optical isolators and circulators with potentials for application in cryogenic microwave devices. As microwave properties of YVO4 are not known, we measured the complex permittivity at frequency of 25 GHz using the Hakki-Coleman dielectric resonator technique in the temperature range from 13 K to 80K. The εr of YVO4 turned out to be similar to that of sapphire, one of popular dielectric materials used at microwave frequencies. Measured loss tangent of YVO4 was of the order of 10−6 at cryogenic temperatures. As Yttrium Vanadate is easy to fabricate and machine, it may replace the expensive sapphire in some microwave applications.
