Solid Generation in a Thermoacoustic Microspace

摘要

Using and exact three-dimensional, Green's function solution to the thermoelastic equations in semi-infinite solid, we have calculated the relative generation efficiencies of thermal waves, longitudinal acoustic waves and transverse acoustic waves induced by a periodically modulated beam of light or particles. The angular distribution and strengths of energy transfer and momentum transfer contributions are compared. Scattering and mode-conversion effects are discussed.
