Superconducting Whispering Gallery Modes
Proposes confining microwave fields in vacuum between patterned aluminum rings on two wafers inside a cylindrical cavity, keeping fields away from lossy dielectric and copper walls. It works through the geometry and mounting, then simulates how mode frequency and Q depend on ring radius, thickness, inner-circle offset and misalignment, separating good whispering-gallery modes from parasitic ones.
- Goals: wafer-scalable cQED, flux bias, measuring thin-film Q
- Ring transmission-line picture with two degenerate whispering-gallery modes
- Practical issues: wafer spacing, springs and indium seal, thermalization, vortices
- Simulated frequency and Q vs. radius, thickness, offset, and alignment
Summary and key points drafted by a language model from the slides, not yet reviewed by me. The slides are the source.
