We present the results of an experimental effort to generate squeezed microwave radiation
using the phase-sensitive gain of a Josephson parametric amplifier. To facilitate the …

The review presents a theoretical framework for understanding submillimeter detection
using an optical photodiode theory. Both gain and noise in the superconductor-insulator …

The high sensitivity detection of terahertz radiation is crucial for many chemical sensing,
biomedical imaging, security screening, nondestructive quality control, high-data-rate …

Superconducting detectors will play an increasingly significant role in astrophysics,
especially at millimeter through far-IR wavelengths, where the scientific opportunities …

A quasi-optical SIS mixer designed for efficient radiation coupling is described. The mixer
uses a twin-slot antenna which has the advantages of a good beam pattern and a low …

We present the design, modeling, construction, and characterization of a sideband
separating heterodyne receiver that covers the frequency range from 600 to 720 GHz. The …

There are in use at present three different ways of deducing the receiver noise temperature
TR from the measured Y-factor, each resulting in a different value of TR. The methods differ …

A quasi-optical heterodyne receiver using a Pb-alloy superconductor-insulator-
superconductor (SIS) tunnel junction as the detector and a planar logarithmic spiral antenna …

The microwave frequency range is home to a large amount of cosmologically crucial signals
including the cosmic microwave background, emission from high redshift galaxies, and …

Abstract” SuperMix” is a software library written to aid in the calculation and optimization of
the signal and noise performance of high-frequency circuits, especially those including …
