| Abstract | Second-harmonic generation in non-linear media is investigated. A normal mode analysis is proposed based on the Westervelt equation under the second-order approximation in nonlinear acoustics. This model takes into consideration attenuation, diffraction and nonlinear effects, together with dispersion. The fundamental and second harmonic is examined. The derived method is evaluated by 2-D analytical formulas which apply to tissue medium. |
