Found in many terahertz (THz) and submillimeter-wave systems, GaAs Schottky diodes
continue to be one of the most useful THz devices. As a low-parasitic device that operates …

In situ research of cometary chemistry began when measurements from the Giotto mission at
Comet 1P/Halley revealed the presence of complex organics in the coma. New telescopes …

Sub-terahertz-and terahertz-band—that is, from 100 GHz to 10 THz—communication
technologies will be required for next-generation (6G and beyond) wireless communication …

We examine the evolution of the water production of comet 67P/Churyumov–Gerasimenko
during the Rosetta mission (2014 June–2016 May) based on in situ and remote sensing …

Heat transport and ice sublimation in comets are interrelated processes reflecting properties
acquired at the time of formation and during subsequent evolution. The Microwave …

We report on the design, fabrication, and testing of a new generation of all-solid-state
frequency-multiplied terahertz sources providing up to ten times more output power at room …

Terahertz (THz) wave manipulation, especially the beam deflection, plays an essential role
in various applications, such as next-generation communication, space exploration, and …

This chapter reviews the estimates of the dust-to-gas and refractory-to-ice mass ratios
derived from Rosetta measurements in the lost materials and the nucleus of 67P/Churyumov …

This comprehensive study delves into the significance of asteroid research and proposes a
systematic classification consisting of seven distinct categories. Initially, a concise definition …

This article presents some aspects of the technology of terahertz heterodyne receiver front-
ends dedicated to astrophysics, planetary and atmospheric sciences. It focuses on …
