Transmission of Sub-millimetre Waves in Fog

Naturevolume 212pages387388 (1966) | Download Citation



WE wish to report the results of experiments aimed at verifying the prediction that sub-millimetre waves would be scattered relatively little by fog. The availability of a stimulated emission source of radiation of wavelength 0.337 mm1, at which frequency the atmosphere is relatively transparent (Fig. 1), has made measurements possible, but the number of observations has been severely limited by the rarity of dense natural fogs on the sites available to us.
