Single-crystal dielectric resonators for low-temperature electronics applications
Jerzy Krupka , Janina E Mazierska
AbstractComputed properties of high-Q factor sapphire, YAG, SrLaAlO4, LaAlO3, rutile, and quartz dielectric resonators (DR's) operating on whispering-gallery TE011 and TE011 modes are presented in this paper. Resonators with a superconducting metal or partly superconducting partly metal shield are considered. For whispering-gallery-mode resonators, dielectric losses determine upper limit for their Q factors, while for TE011-mode resonators, their Q factors are usually limited by conductor losses. Single-crystal TE016-mode resonators would have Q factors determined by both dielectric and conductor losses, and dominant loss mechanism depends on crystal losses and shield geometry. Geometric factors that allow evaluation of conductor losses of TE011- and TEole-mode resonators are given for different DR structures.
