Key components of systems operating at high millimeter wave and sub-millimeter
wave/terahertz frequencies, a 140-GHz fundamental mode voltage controlled oscillator …

This work presents one of the most powerful methods of plasma diagnosis in exquisite
detail, to guide researchers in the theory and measurement techniques of light scattering in …

This book is the second edition of the original book by John Sheffield, published in 1975,
which for a long time has been a standard textbook and reference book for graduate …

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

Aims. The prime motivation of this project was to design and build a state-of-art mm-wave
heterodyne receiver system to enhance the observing throughput of the IRAM 30-m …

Our Universe is most radiant at terahertz frequencies (0.1–10.0 THz)(ref.), providing critical
information on the formation of the planets, stars and galaxies, as well as the atmospheric …

The state-of-the art of terahertz heterodyne receivers are reviewed. Emphasis is placed on
front-end components such as mixers and local oscillators. The back-end technology is …

We report the first demonstration of an all solid-state heterodyne receiver that can be used
for high-resolution spectroscopy above 2 THz suitable for space-based observatories. The …

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 …

We report on a heterodyne receiver designed to observe the astrophysically important
neutral atomic oxygen [OI] line at 4.7448 THz. The local oscillator is a third-order distributed …
