INFORMATION has recently been disclosed about the absorption band in the oxygen molecule for electromagnetic radiation of wave-length in the region of 5 mm.1. This communication gives preliminary details of an experimental investigation on propagation over sea of waves in this wave-length region.

ESR at millimetre and sub-millimetre wave frequencies
IEE Colloquium on Terahertz Technology and its Applications, 1997The advantages, applications and design principles behind using electron spin resonance (ESR) spectrometers at millimetre and sub-millimetre wave frequencies are outlined. A sensitive quasioptical ESR spectrometer operating in the frequency range 80-200 GHz and temperature range 2.5 K to 250 K is described and some of the future technical challenges in

Millimetre and Submillimetre Waves
Electronics and Power, 1970F A Benson (Ed.) London: Butterworth 1970 pp 579 price £12 12s The region of millimetre and submillimetre wavelength is a part of the electromagnetic spectrum which has only recently begun to be exploited. This book is a compendium of information on the generation, transmission and detection of waves in this region.

The generation of millimetre waves
Proceedings of the IEE - Part B: Radio and Electronic Engineering, 1955Problems in the generation of millimetre waves are considered, and further study of sparked generators is found desirable. A contribution is made to the simple theory of such generators. Experiments made to verify the theory are not wholly successful, but their evidence, together with that of other workers, strongly suggests that this simple theory is ...

Terrain imaging millimetre wave radar
7th International Conference on Control, Automation, Robotics and Vision, 2002. ICARCV 2002., 2004This paper presents an overview of the work being conducted by the Australian Centre for Field Robotics (ACFR) and the CRC for mining technology and equipment (CMTE) into sensors and systems for real-time environment imaging. Radar is perhaps the only sensor capable of performing imaging tasks in environment where high levels of dust, water vapour, and

Millimetre wave spectroscopy of PANHs: phenanthridine
Phys. Chem. Chem. Phys., 2007The pure rotational spectrum of phenanthridine (C(13)H(9)N), a small polycyclic aromatic nitrogen heterocycle (PANH), has been measured from 48 to 85 GHz employing Stark modulated millimetre wave absorption spectroscopy of a supersonic rotationally cold molecular beam.

Proceedings of the IEE Part C: Monographs, 1956
The construction and performance of a pulsed-millimetre-wave magnetron are described. The performance is compared with that of a “parent” valve, using Slater's scaling laws, and with theoretical standards. Some problems encountered in designing the valve and in holding close tolerances on the performance are discussed.

Commercial and scientific applications of millimetric and sub-millimetric waves
Radio and Electronic Engineer, 1979Until recently, the application of microwave systems has been hampered by the relatively large and expensive equipment, particularly in the millimetre and submillimetre-wave range. The development of more reliable and efficient solid-state sources up to the submillimetre-wave range has now stimulated new interest in commercial applications.
