Thermophysical and mechanical properties of active membranes for photoacoustic generators of forced acoustic oscillations

Abstract

Thermophysical and mechanical properties of active membranes for photoacoustic generators of forced acoustic oscillations are studied. Dependencies of photoacoustic generators output characteristics versus active membranes for forced acoustic oscillations are found out for different heat power densities within the structures studied. Keywords: Photoacoustic generator, forced acoustic oscillations, linear oscillations, full width at half maximum, active membrane.
