Reflection and Refraction at a Single Interface 5.1 the Behaviour of Light at a Dielectric Interface
نویسنده
چکیده
The previous Chapters have been concerned with the propagation of waves in empty space or in uniform, homogeneous media. It is now time to introduce more complicated geometries, building towards those appropriate to optical waveguides. We begin with a qualitative discussion of the phenomena that occur when light strikes a dielectric interface. Figure 5.1-1 shows a plane wave incident at an angle θ1 on two semi-infinite media, with refractive indices n1 and n2, respectively. These are chosen such that n1 > n2.

Wave Reflection and Refraction at the Interface of Triclinic and Liquid Medium
A Mathematical model has been considered to study the reflection and refraction phenomenon of plane wave at the interface of an isotropic liquid medium and a triclinic (anisotropic) half-space. The incident plane qP wave generates three types of reflected waves namely quasi-P (qP), quasi-SV (qSV) and quasi-SH (qSH) waves in the tric...
متن کاملRefraction at the Interface of a Lossy Metamaterial
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...
متن کاملReflection and Transmission of Longitudinal Wave at Micropolar Viscoelastic Solid/Fluid Saturated Incompressible Porous Solid Interface
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...

Nanocomposite materials, including noble metal nanoparticles embedded in a dielectric host medium, are interesting because of their optical properties linked to surface plasmon resonance phenomena. For studding of nonlinear optical properties and/or energy transfer process, these materials may be excited by ultrashort pulse laser with a temporal width varying from some femtoseconds to some hund...
متن کاملEffect of morphology and nonbounded interface on dielectric properties of plasma sprayed BaTiO3 Coating
In this research, BaTiO3 thick deposit has been successfully sprayed by air plasma spray. The microstructure and dielectric properties of thick films were investigated by secondary electron microscopy (SEM) and LCR meter respectively. XRD measurement was carried out on plasma sprayed BaTiO3. The results illustrate differences in the crystal structure between plasma sprayed coatings and feed sto...
