Abstract
Electromagnetic momentum is a fundamental physical concept that has be en demonstrated experimentally and incorporated theoretically in vario us areas of physics. In spite of the weak character of the electromagn etic momentum transfer process, the combination of latter-day, high-en ergy laser light sources and microminiature mechanical elements sugges ted the possibility of optical excitation of these structures. One out come of the present theoretical analysis is the prediction of an optop iezic effect wherein electromagnetic momentum causes a mechanical stre ss on a dielectric layer. If this is a valid prediction, such an optic ally induced, expansional pressure effect could be utilized as an exte nsional optical-to-mechanical transduction means.
