Ultrasound coefficient of nonlinearity imaging

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2015
Imaging the acoustical coefficient of nonlinearity, β, is of interest in several healthcare interventional applications. It is an important feature that can be used for discriminating tissues. In this paper, we propose a nonlinearity characterization method with the goal of locally estimating the coefficient of nonlinearity.

Nonlinear directional coupler with variable coupling coefficient and variable nonlinear refractive index coefficient

Optics Communications, 2005
In this paper, we report on the study of the coupled mode equations for nonlinear directional coupler (NLDC) in which both linear coupling coefficient and nonlinear refractive index coefficient are functions of propagation distance. We show, for the first time, to the best of our knowledge, that the equations for the general case can be transformed to ...

Nonlinear Burnett coefficients

Physical Review A, 1988
We derive exact equilibrium fluctuation expressions for the nonlinear Burnett coefficients for the electrical conductivity of a fluid. The Burnett coefficients define a Taylor-series expansion of the conductivity in powers of the electrical current density.

Effective nonlinear coefficients of strongly nonlinear dielectric composites

Journal of Applied Physics, 2007
The effective medium theory is used to model a two-phase strongly nonlinear dielectric composite. More general effective nonlinear coefficients are determined which are not limited to the case of dilute inclusions. Our results obtained by using the decoupling technique and the variational method are compared and are in agreement with the experimental ...
