The present article deals with the two parts: (i)The propagation of plane waves in a microstretch thermoelastic diffusion solid of infinite extent. (ii)The reflection and transmission of plane waves at a plane interface between inviscid fluid half-space and micropolar thermoelastic diffusion solid half-space.It is found that for two-dimensional model, there exist four coupled longitudinal waves...

It is shown that information transmission inside a cell can occur by means of mechanical waves transmitted through DNA. The propagation of the waves is strongly dependent on the shape of the DNA thus proteins that change the shape of DNA can alter signal transmission. The overall effect is a method of signal processing by DNA binding proteins that creates a ”cellular communications network”. Th...

The evolution of internal solitary waves (ISWs) propagating in a rotating channel is studied numerically in the framework of a fully-nonlinear, nonhydrostatic numerical model. The aim of modelling efforts was the investigation of strongly-nonlinear effects, which are beyond the applicability of weakly nonlinear theories. Results reveal that small-amplitude waves and sufficiently strong ISWs evo...

The reflection and transmission of internal waves at a horizontal interface between layers constant buoyancy frequency are treated. This is simple model the atmospheric tropopause. weakly nonlinear obey Schrödinger equation away from interface. horizontally periodic vertically confined to long packet. interfacial conditions formally taken third order, include higher-order linear as well effects...

Abstract Between 5% and 25% of the total momentum transferred between atmosphere ocean is transmitted via growth long surface gravity waves called “swell.” In this paper, we use large-eddy simulations to show that swell-transmitted excites near-inertial drives turbulent mixing deepens a rotating, stratified, boundary layer. We find currents are less effective at producing turbulence layer than ...

Acoustics Willis media, known as bianisotropic acoustic incorporate additional coupling between pressure and velocity momentum volumetric strain in their constitutive equation. The extra terms have a significant influence on wave behavior. In this paper, the unusual phenomena relevant to interfaces homogeneous media are theoretically studied. We show that offer more flexible control front energ...

The memory effect in disordered systems is a key physical phenomenon that has been employed for optical imaging, metrology, and communication through opaque media. Under the conventional effect, when incident beam tilted slightly, transmitted pattern tilts same direction. However, "memory" limited its angular range tilt Here, we present general approach to customize by introducing an operator. ...

To simulate VFEL operation the superradiance from a short electron pulse moving in a volume diffraction grating is studied. It is supposed that Bragg condition for emitted photons is fulfilled and dynamical diffraction takes place. Spectral-angular distributions for transmitted and diffracted waves are derived. It is shown that the optimal geometry for superradiance exists and it is determined ...

In past decades, considerable effort has been devoted to the phenomenon of wave-induced liquefaction, because it is one of the most important factors for analysing the seabed and designing marine structures. As waves propagate and fluctuate over the ocean surface, energy is carried within the medium of the water particles. This energy could be transmitted into the seabed, which results in the r...
