Microwave properties of Yttrium Vanadate at cryogenic temperatures
Mohan V. Jacob, Janina E. Mazierska, Jerzy Krupka +2
Yttrium Vanadate (YVO4) is a birefringent crystal material used in optical isolators and circulators with potentials for application in cryogenic microwave devices. As microwave pr…
Surface resistance measurements of HTS thin films using SLAO dielectric resonator
Mohan V. Jacob, Janina E. Mazierska, Kenneth Leong +2
Surface resistance of HTS films is typically measured using Sapphire dielectric rod resonators enclosed in a copper cavity. In this paper we present surface resistance measurements…
Complex Permittivity Measurements at Variable Temperatures of Low Loss Dielectric Substrates Employing Split Post and Single Post Dielectric Resonators
Janina E. Mazierska, Mohan V. Jacob, Dimitri O. Ledenyov +1
A split post dielectric resonator in a copper enclosure and a single post dielectric resonator in a cavity with superconducting end-plates have been constructed and used for the co…
Microwave characterisation of CaF2 at cryogenic temperatures using a dielectric resonator technique
Mohan V. Jacob, Janina E. Mazierska, Dimitri O. Ledenyov +1
Properties of calcium fluoride (CaF2) have been well researched at UV, visible and IR range of frequencies, but not at ultra high frequencies. In this work we report the loss tange…
Precise microwave characterization of MgO substrates for HTS circuits with superconducting post dielectric resonator
Janina E. Mazierska, Dimitri O. Ledenyov, Mohan V. Jacob +1
Accurate data of complex permittivity of dielectric substrates are needed for efficient design of HTS microwave planar circuits. We have tested MgO substrates from three different…
