BACK-SCATTERING OF 3.21-CM RADIATION BY WATER BUBBLES
Abstract
Calculations were made of the back-scattering of 3.21-cm waves from water bubbles ranging in diameter, D, from 0.2 to 5.0 cm. Film thicknesses between 2 and 1000 microns were considered. As the diameter increases the back-scattering crosssection shows a gradual upward trend but sharp minima occur at intervals of D which are at integral values of 1/2 wave length. As the film thickness increases there is a general increase of the back-scattering cross-sections with the increase being most pronounced at small film thicknesses. Except at intervals of D close to 1/2 wave length, the back-scattering cross-sections of bubbles are higher than that from water spheres of the same mass. (Author)
