Superconducting Microstrip-Fed Antenna Coupled to a Microwave Kinetic Inductance Detector

A proper antenna to couple to a microstrip Microwave Kinetic Inductance Detector (MKID) is designed and simulated. A twin-slot microstrip-fed inline antenna is designed for frequency band of 600-720~GHz integrated with an elliptical lens and coupled to the MKID. A systematic design procedure for design of such antenna with microstrip inline feeding is presented. Whole structure of lens and twin...

Transition-edge superconducting antenna-coupled bolometer

We report test results for a single pixel antenna-coupled bolometric detector. Our device consists of a dual slot microstrip antenna coupled to an Al/Ti/Au voltage-biased transition edge superconducting bolometer (TES). The coupling architecture involves propagating the signal along superconducting microstrip lines and terminating the lines at a normal metal resistor colocated with a TES on a t...

Lens-Antenna Coupled Superconducting Hot-Electron Bolometers for Terahertz Heterodyne Detection and Imaging

A plasmonic antenna-coupled superconducting near-IR photon detector.

The extremely small size of plasmonic antennas has made it difficult to integrate them with nanoscale detectors that require electrical leads, as the leads tend to degrade the resonant properties of the antenna. We present a design for integrating a plasmonic antenna with a nanoscale superconducting transition-edge sensor (TES) with electrical leads. Numerical simulations demonstrate high-effic...
