Materials and characterization using acoustic nonlinearity parameters and harmonic generation - Effects of crystalline and amorphous structures
Abstract
The effects of material structure on the nonlinearity parameters are reviewed. Problems discussed include definition of nonlinearity parameters, square-law nonlinearity and collinear beam-mixing, structure dependence of the nonlinearity parameters, negative nonlinearity parameters, and implications for materials characterization.
