Measurements of harmonic generation in a focused finite-amplitude sound beam
Averkiou, Michalakis A.; Hamilton, Mark F. (1995)Measurements of harmonic generation in the sound field radiated by a focused circular piston source are compared with numerical calculations based on the nonlinear parabolic wave equation. The large dynamic range and high ...

Nonlinear distortion of short pulses radiated by plane and focused circular pistons
Averkiou, Michalakis A.; Hamilton, Mark F. (1997)Detailed measurements of finite-amplitude pulses radiated by plane and focused circular pistons in water are presented. Comparisons of time waveforms and frequency spectra, both on and off axis, are made with numerical ...

Second-harmonic generation in a sound beam reflected and transmitted at a curved interface
Makin, Inder Raj S.; AVERKIOU, MICHALAKIS A.; Hamilton, Mark F. (2000)This article presents a model for second-harmonic generation in a sound beam that is reflected from or transmitted through a curved interface. Propagation in homogeneous fluids is assumed. Simple analytic solutions are ...

Self-demodulation of amplitude- and frequency-modulated pulses in a thermoviscous fluid
Averkiou, Michalakis A.; Lee, Yang-Sub; Hamilton, Mark F. (1993)The self-demodulation of pulsed sound beams in a thermoviscous fluid is investigated experimentally and theoretically. Experiments were performed in glycerin at megahertz frequencies with amplitude- and frequency-modulated ...
