The theory of photomechanical excitation in a Langmuir monolayer
Abstract
A theory for the excitation of flexural waves by an electromagnetic field in a Langmuir monolayer is proposed which is based on the phenomenon of surface photoeffect and the associated charge separation along the monolayer molecules. The flexural waves are excited by the resulting electrostatic longitudinal compression forces which cause a parametric buildup of the wave. The conditions necessary for this excitation mechanism to be implemented are examined; the intensity of the electromagnetic wave is estimated.
