The concept of a fully superconducting integrated receiver is developed and experimentally
tested. This single-chip sub-mm wave receiver includes a planar antenna integrated with a …

The spin torque, effect that occurs in nanometre-scale magnetic multilayer devices can be
used to generate steady-state microwave signals in response to a dc electrical current …

This paper reviews the present status and future perspectives of discrete Josephson junction
arrays for applications as sub-mm wavelength radiation sources. It is intended to cover the …

A review of recent developments in the techniques and instrumentation used for sensitive
millimeter–and submillimeter–wave astronomical observations is given. The capabilities of …

Lightweight and compact ultra-sensitive submm Superconducting Integrated Receiver
(SIR)[1] with low power consumption is very attractive for both radioastronomical research …

This study proposes a spintronic based compact tunable nano‐sized RF oscillator. The
proposed design provides parametric performance improvement as compared with the …

Terahertz frequencies, somewhat loosely defined as those in the range 100 GHz-10 THz,
form a significant region in the electromagnetic spectrum that has not yet been opened up …

Radiation from a linear array oscillator with a spiral antenna has been measured using an
off-chip coupled bolometer. The array oscillator has a distributed array structure with 300 …

We report heterodyne measurements of Josephson microwave radiation emitted by a
parallel array of small superconductor-insulator-superconductor (SIS) junctions at …

The cylindrical lens with flat sides, which has the focal point just on the surface of the lens, is
developed by using an artificial low-loss dielectric material, and the design of the lens is also …
