Many exciting terahertz imaging applications, such as non-destructive evaluation,
biomedical diagnosis, and security screening, have been historically limited in practical …

Sensing ultra-low magnetic fields has various applications in the fields of science, medicine
and industry. There is a growing need for a sensor that can be operated in ambient …

Thermal Kinetic-Inductance Detectors (TKIDs) combine the excellent noise performance of
traditional bolometers with a radio frequency multiplexing architecture that enables the large …

Sub-THz imaging techniques are currently emerging with applications especially in security
screening requiring higher throughput in mass transit and public areas. In the context of …

Current state-of-the-art security video cameras operating in the THz regime employ up to a
few hundred detectors together with optomechanical scanning to cover an adequate fieldof …

Passive imaging cameras at submillimeter wavelengths with large format focal plane arrays
(FPAs) are being developed as the next generation of security screening systems. In this …

In this thesis I describe work on developing theoretical and numerical models of supercon-
ducting thin-film microwave resonators. Superconducting resonators are used in a variety of …

An electrothermal model of kinetic inductance detectors is described. The non-equilibrium
state of the resonator's quasiparticle system is characterized by an effective temperature …

We demonstrate strong negative electrothermal feedback accelerating and linearizing the
response of a thermal kinetic inductance detector (TKID). TKIDs are a proposed highly …

Different terrestrial terahertz applications would benefit from large-format arrays, operating in
compact and inexpensive cryocoolers at liquid helium temperature with sensitivity, limited …
