Techniques for millimetre-wave imaging
SPIE Proceedings, 2004This paper reviews the formation of an image with coherent and incoherent radiation. It discusses the various mm-wave methods for electronic beam-forming and beam-steering such as phased array, leaky-wave antennas, up-conversion, tapped delay lines and digital beam-forming techniques.

Millimetric Waves Technologies: Opportunities and Challenges
2011Providing an available wideband and better antenna beam forming are two good profits of millimeter wave (mmWave) technology. MmWave technology makes radio systems lighter and smaller and radars more precise. Today, commercial MmWave equipment work below 90GHz frequencies. MmWave radios work to transport Internet traffic in the backhaul of communication

Millimetre-wave spectrum of CF3Br
Journal of the Chemical Society, Faraday Transactions 2, 1982The millimetre-wave rotational spectra of CF379Br and CF381Br have been measured in the ground and low-lying excited states. Analysis of the ground-state spectra has yielded precise values of the rotational and centrifugal distortion constants, as well as bromine nuclear quadrupole coupling constants.

In the millimetre wave frequency range, scaling becomes a problem so that copies of microwave devices become difficult to manufacture with adequate accuracy. Then special techniques suitable only for millimetre wave devices become necessary. This chapter concentrates on those techniques which are peculiar to ferrite devices operating at millimetre wave

The millimetre wave future of telecommunications
Physics Bulletin, 1969There now appears little doubt that telecommunications with millimetric microwaves will play a leading part in the transmission of visual, audio and digital information. The prospects for the millimetric region of the electromagnetic spectrum appear much more attractive than for the wavelengths at which lasers can operate, for a number of reasons.
