As immersion lithography is extended to ever increasing resolution, the resulting propagation angles in the materials involved become closer to grazing than to normal incidence. Classical laws of refraction and reflection cannot be used with either assumption however, as a collection of angles may exist across the entire range. Fresnel reflection at these angles becomes large enough that small ...

In this paper, the reflection and refraction of longitudinal wave from a plane surface separating a micropolar viscoelastic solid half space and a fluid saturated incompressible half space is studied. A longitudinal wave (P-wave) impinges obliquely at the interface. Amplitude ratios for various reflected and transmitted waves have been obtained. Then these amplitude ratios have been computed nu...

apart expressing the cause of the reflection of light from the surface of polished objects, ibn al-haytham in his al-manāẓir claims that the acceptance or rejection of light by these objects is only due to their polished surfaces and have nothing to do with their solidity, because the reflection of light from the surface of soft polished objects such as water is also possible. kamāl al-dīn al-f...

Surface gravity waves interact with the flexural to generate whose characteristics are triggered for higher values of lateral compressive stress multiple propagating wave modes. This investigation examines scattering obliquely incident due articulation in two semi-infinite heterogeneous floating elastic plates finite water depth within a blocking dynamics regime. The dispersion curve demonstrat...

The optical scattering, absorption, and polarization properties of human retinal tissues are investigated for a number of laser wavelengths in the visible range. The indices of refraction of these tissues are determined by applying Brewster's law. The inverse adding doubling method based on the diffusion approximation and radiative transport theory is applied to the measured values of total dif...

We report the transmission characteristics of split-ring resonator and left-handed metamaterials (LHM) in the microwave frequency regime. A left-handed transmission band is observed at the frequencies where both dielectric permittivity and magnetic permeability are negative. The reflection characteristics of ordered and disordered LHMs are studied. The two-dimensional LHM structure is verified ...

Abstract Transverse (Hall-effect) and Goos–Hänchen shifts of light beams reflected/refracted at planar interfaces are important wave phenomena, which can be significantly modified enhanced by the presence intrinsic orbital angular momentum (OAM) in beam. Recently, optical spatiotemporal vortex pulses (STVPs) carrying a purely transverse OAM were predicted theoretically generated experimentally....

The refraction phenomenon at the interface of an ordinary material and a lossy metamaterial has been investigated. For oblique incidence on the lossy metamaterial, the planes of constant amplitude of the refracted wave are parallel to the interface and the plane of constant phases make a real angle with the interface (real refraction angle). The real refraction angle and hence, the real refract...
