STATIC ELECTRIC FIELDS ON SINUSOIDAL SURFACES.

Abstract

The purpose of this study was to evaluate the possibility of detecting sound waves on the surface of the sea by their effect on the charge distribution of the ambient d-c electric field. It is assumed that sound waves produce small sinusoidal variations in height on the surface of water. These surface waves have a wavelength determined by the frequency of the sound wave and its velocity on the surface of the water. In general, the wavelength of sound waves is much shorter than the characteristic length of other waves normally present on the surface. The ratio of the static electric field at a peak to that at a neighboring trough on conducting sinusoidal surfaces with various period-amplitude ratios is determined. This ratio can be used to determine the maximum variation in field intensity at the surface of a passing conducting wave.
