A problem of reflection and transmission of a plane shear wave incident at a corrugated interface between transversely isotropic inhomogeneous and visco-elastic half-spaces is investigated. Applying appropriate boundary conditions and using Rayleigh’s method of approximation expressions for reflection and transmission coefficients are obtained for the first and second order approximation of the...

The existing theory for wave propagation through a soil layer are not compatible with the real soil layers because in the theory the layers are flat and the sub-layers are parallel, while in real the soil layers are not flat and they may not be parallel. Thus, wave propagations through a corrugated interface are so important. In this paper, a two-dimensional SH-wave propagation through a corrug...

Wideband suppression of zero order and relevant strongly asymmetric transmission can be obtained in photonic crystal gratings that are made of linear isotropic materials and show the broken structural (axial) symmetry, even if zero diffraction order may be coupled to a Floquet-Bloch (FB) wave at the incidence and exit interfaces. The studied mechanism requires that the peculiar diffractions at ...

This paper addresses an important issue of light throughput of a metal-coated tapered tip for scanning near-field microscope (SNOM). Corrugations of the interface between the fiber core and metal coating in the form of parallel grooves of different profiles etched in the core considerably increase the energy throughput. In 2D FDTD simulations in the Cartesian coordinates we calculate near-field...

An apparently idiopathic interface diseasee in a 2-year-old Boer billy goat is described. Clinical features of the disease were the presence of a pruritic multiple focally disseminated dermatitis with flat-topped, angular, scaly plaques and papules with corrugated surfaces in the skin of virtually the entire body. The aetiology of the disorder in the described case is unknown.

Medium vibration properties to characterize interface layers and quality of bonding can be examined by an ordinary approach using homogeneous waves or by a more general inhomogeneous ~or complex harmonic! wave scattering technique. It is known that only particular inhomogeneous plane waves can stimulate eigenvibrations of a given structure, and not the homogeneous wave. The reflection and trans...

Localized energy exchange and mechanical coupling across a few nm gap at a corrugated graphene-substrate interface remain great challenges to study. In this work, an infrared laser is used to excite an unconstrained epitaxial graphene/SiC interface to induce a local thermal non-equilibrium. The interface behavior is uncovered using a second laser beam for Raman excitation. Using Raman peaks for...

A new method for the composite rolling of 304/Q345R was explored in present study. The interface plate studied using a scanning electron microscope (SEM) and electron-backscatter diffraction (EBSD). results showed that formed with corrugated connections, increasing length interface. Furthermore, elongation relative to original wave horizontal were 29.43 % 59.12 %, respectively. became 3D ripple...
