Tunable 3D dielectric resonator using a thermoconductive VO^sub 2^ material

A temperature-based tunable dielectric resonator is presented showing a tunability of 20 MHz around 11.8 GHz when heated with a drop of the quality factor from 4000 to 286. The puck-shaped alumina resonator contains a thin sapphire sheet coated with VO^sub 2^. An overview of the thermoconductive VO^...

Description
Summary:A temperature-based tunable dielectric resonator is presented showing a tunability of 20 MHz around 11.8 GHz when heated with a drop of the quality factor from 4000 to 286. The puck-shaped alumina resonator contains a thin sapphire sheet coated with VO^sub 2^. An overview of the thermoconductive VO^sub 2^ material used is presented. The design and simulations of the resonator are presented along with the fabricated structure and measurements.
