The discovery of hot-electron phenomena in a thin superconducting film in the last century
was followed by numerous experimental studies of its appearance in different materials …

This paper reviews the state of rapidly emerging terahertz hot-electron nanobolometers
(nano-HEB), which are currently among of the most sensitive radiation power detectors at …

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 …

The submillimetre or terahertz region of the electromagnetic spectrum contains
approximately half of the total luminosity of the Universe and 98% of all the photons emitted …

A novel dielectric lens antenna with a broadband integrated waveguide-based feed and an
optimized tapered extension is presented for low terahertz frequencies. The antenna …

Dielectric lens antennas are attracting a renewed interest for millimeter-and submillimeter-
wave applications where they become compact, especially for configurations with integrated …

Schottky diodes are well-known nonlinear elements allowing for effective detection and
mixing of electromagnetic radiation in the range through microwave to terahertz. Although …

We have measured the noise temperature of a single, sensitive superconducting NbN hot
electron bolometer (HEB) mixer in a frequency range from 1.6 to 5.3 THz, using a setup with …

This paper presents millimeter-wave and terahertz double bow-tie slot antennas on a
synthesized elliptical silicon lens. Two different antennas are designed to cover 0.1-0.3 and …

This paper examines the performance of dual-linear sinuous antennas on silicon extended
hemispherical silicon dielectric lenses. A theoretical impedance of 106 Ω is identified based …
