A Microwave Radiation Monitor

Journal of Applied Meteorology, 1976
Abstract A microwave radiation monitor designed for rapid measurement of microwave power density in the field is described. The instrument incorporates a broad-band spiral antenna whose design is based on a knowledge of the field pattern of a circular loop antenna.

Microwave Radiation from the Sun

Journal of the Franklin Institute, 1945
During the summer months of both 1942 and 1943, the writer and certain of his associates observed a small but measurable amount of microwave radiation coming from the sun. This appeared as random noise in the output of a conventional double-detection radio receiver designed to work at centimeter wave lengths.

Ocular Effects of Microwave Radiation

1967
Abstract : Rabbit eyes were irradiated utilizing qualitative and quantitative control of the microwave energy entering the eye. In all cases, the left eye was exposed to either pulsed or continuous wave emission at 5400 megacycles (megahertz) per second and the right eye served as an unexposed control.

A Study of Microwave Radiation Leakage From Microwave Ovens

American Industrial Hygiene Association Journal, 1970
There has been an increase in the use of microwave ovens for cooking foods. Their use results in a considerable reduction in cooking time over conventional ovens. A study was made of 187 commercial use ovens to determine the extent of leakage of microwave radiation.

Microwave Radiation Hazards around Large Microwave Antenna

American Industrial Hygiene Association Journal, 1973
The microwave radiation hazards associated with the use of large antennas become increasingly more dangerous to personnel as the transmitters go to ever higher powers. The near field area is of the greatest concern,, It has spill over from sub-reflector and reflections from nearby objects. Centimeter waves meeting in phase will reenforce each other and

Microwave noise radiators

International Journal of Infrared and Millimeter Waves, 1997
For the purposes of Microwave Active Radiometry (1), three noise radiators were developed and tested. One is a conventional noise diode source in a rectangular R-100 waveguide with a 6-dB horn attached, other two noise radiators are made as half-wave dipoles with noise diodes installed.

On microwave transition radiation

Technical Physics, 1998
The energy of the radiation emitted by an ultrarelativistic (1 GeV) electron at a transition from vacuum into yttrium iron garnet I3Fe5O12 at the ferromagnetic resonance frequency (vacuum wavelength 3 cm) is estimated. The energy at this frequency was found to be 10−13 eV·s.

Cerenkov Radiation at Microwave Frequencies

1961
Publisher Summary This chapter describes the various aspects of Cerenkov radiation at microwave frequencies. Cerenkov radiation may be considered the electromagnetic analog of the acoustic shock wave which is produced when a projectile moves through a medium at a velocity which exceeds the velocity of wave propagation in the medium.

The microwave background radiation

Nuclear Physics B - Proceedings Supplements, 1992
The microwave background radiation was first detected in 1965 by A. Penzias and R. Wilson, who received the 1978 Nobel Prize for Physics for this measurement [see Wilson (1983b) for his delightful account of this discovery].
