REFRACTION OF FINITE-HEIGHT AND BREAKING WAVES

numerical analysis of combined refraction and diffraction of waves

refraction and diffraction combination of waves, is very important and applicable problem in coastal engineering (e.g. for designing break - water). however, formulation of this phenomen and numerical solution is very difficult. in this study, a numerical algorithm based on the mild slop sea bed theory is presented to obtain the appropriate governing equations of combined refraction diffraction...

Refraction of dispersive shock waves

We study a dispersive counterpart of the classical gas dynamics problem of the interaction of a shock wave with a counter-propagating simple rarefaction wave often referred to as the shock wave refraction. The dispersive shock wave (DSW) refraction due to its head-on collision with the centred rarefaction wave (RW) is considered in the frameworks of the one-dimensional defocusing nonlinear Schr...

Refraction of waves in excitable media

Waves in chemically excitable systems can refract when impinging on an interface between regions of different reaction kinetics and/or diffusion constants. Here we study this process using the thin reaction-zone limit wherein the dynamics of the system can be reduced to the tracking of the boundaries between quiescent and excited regions. We show how to derive an integrodifferential equation fo...

Positive and negative refraction of magnetoinductive waves in two dimensions

Previous studies of magnetoinductive waves in homogeneous media with resonant elements consisting of capacitively loaded metallic loops are extended to the case when a single wave from one medium is incident upon another one. The relationship between the input and output angles and the reflection and transmission coefficients are determined with the aid of the dispersion equation for different ...
