Electrostatic tuning of mechanical and microwave resonances in 3D superconducting radio frequency cavities

We implement a non-contact, external method of simultaneously fine-tuning a mechanical resonator and a superconducting radio frequency (SRF) cavity using a capacitor formed between a silicon nitride membrane and a copper electrode at cryogenic temperatures. The silicon nitride membrane forms a varia...
