Millimeter-wave ICs

2009 IEEE Custom Integrated Circuits Conference, 2009
The rapid increase in the FTs of CMOS devices is starting to show the promise of designing millimeter-wave and even terahertz RF circuits in standard CMOS technologies. What was once the domain of exotic three-five compounds is slowing being supplanted and superseded by silicon technologies. In this millimeter-wave IC session five papers that introduce

Diplexing Millimeter Waves

International Journal of Infrared and Millimeter Waves, 1998
The paper describes a band-splitting filter or diplexer, which splits the incoming spectrum into the sub-bands 120-139 GHz and 141-158 GHz. This diplexer is intended to separate the electron cyclotron emission of a magnetically confined plasma into two subbands and to feed two independent heterodyne radiometers.

Millimeter-wave antennas

Annales Des Télécommunications, 1997
With the continually increasing demand for bandwidth, and the development of components for higher and higher frequencies, millimeter-wave systems are finding numerous applications of a commercial nature rather than being limited to military and scientific applications only.

Millimeter-wave-detected, millimeter-wave optical polarization spectroscopy

The Journal of Chemical Physics, 2005
We report a new form of microwave optical double-resonance spectroscopy called millimeter-wave-detected, millimeter-wave optical polarization spectroscopy (mmOPS). In contrast to other forms of polarization spectroscopy, in which the polarization rotation of optical beams is detected, the mmOPS technique is based on the polarization rotation of ...

Laser-Millimeter Wave Techniques

Applied Optics, 1971
The use of millimeter techniques with lasers has resulted in the stabilization of a laser to an absolute frequency standard. Also, a high resolution infrared spectrometer with the characteristics of a microwave spectrometer has been developed.

Study of millimeter waves in 5G

2021 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2021
The millimeter waves correspond to frequencies in the range 30-300 GHz and, implicitly, to wavelengths in the range 1-10 mm. They will underpin the new generation of mobile communications systems, offering much higher bandwidth, lower latency and the ability to serve a larger amount of users.

Millimeter-Wave Imaging Sensor

SPIE Proceedings, 1986
A dual polarized 3-mm radiometer system, with a mechanically scanned antenna, has been built for use on a small aircraft or RPV to produce near real-time moderate resolution (0.5°) images of the ground. One of the main advantages of this passive imaging sensor is that it is able to provide surveillance information through clouds, smoke, and dust when ...

Near-millimeter waves

Proceedings of the IEEE, 1985
This paper provides a brief overview of the field of near-millimeter waves and serves as an introduction to the five following papers. The nomenclature and spectral regions are defined and a historical summary is given. Brief comments are then given about the contents of the succeeding articles.

Printed millimeter-wave reflectarrays

Annales Des Télécommunications, 2001
Des structures periodiques et quasi-periodiques, imprimees sur un substrat dielectrique peuvent etre employees pour commander les proprietes de reflexion et de transmission des ondes incidentes en fonction de la structure geometrique. Ceci peut etre realise pratiquement independamment pour les deux polarisations.
