Wave-tilt characteristics of EM waves over a two layered earth model.

Nonlinear Bulk Elastic Waves in Layered Solid Wave Guides

During the last decade we have performed theoretical investigations and successful experimental research demonstrating the existence and main properties of bulk strain solitary waves in nonlinearly elastic solid wave guides. Following the topic we present preliminary results on strain soliton propagation in layered wave guides made of PMMA. The obvious physical relevance of data on strain solit...

Nonlinear waves and wave scattering in layered elastic waveguides

Characteristics of head wave in multi-layered half-space

In this article, we analyze the dynamic characteristics of head wave in multi-layered half-space media models with high-velocity layer or low-velocity layer, and the model with a continuous transition-zone between the crust and the mantle by using synthetic seismogram. It is concluded that the dynamic characteristics of head wave are sensitive to the thickness and velocity of the high-velocity ...

A general wave equation for waves over rippled beds

A time-dependent extension of the reduced wave equation of Berkhoff is developed for the case of waves propagating over a bed consisting of ripples superimposed on an otherwise slowly varying mean depth which satisfies the mild-slope assumption. The ripples are assumed to have wavelengths on the order of the surface wavelength but amplitudes which scale as a small parameter along with the botto...

A global investigation of solitary-wave solutions to a two-parameter model for water waves

arises as the equation for solitary-wave solutions to a fifth-order long-wave equation for gravitycapillary water waves. Being Hamiltonian, reversible and depending upon two parameters, it shares the structure of the full steady water-wave problem. Moreover, all known analytical results for local bifurcations of solitary-wave solutions to the full water-wave problem have precise counterparts fo...
