Sommerfeld, and, since then, other ways of deriving the theory have been given,.> > s each bringing out some special feature of the problem. It is the object of this paper to present yet another point of view, which promises to be of practical importance for dealing with situations where the path of propagation lies partly over land and partly over sea. When first approaching the problem of rad...

Design of a two-reflection, non-deviating beam total internal reflection quarterwave phase retarder is presented. The device treats the two main drawbacks of the Fresnel rhomb which are the lateral shift of the emergent beam and sensitivity of the retardance value to errors in the external angle of incidence. In addition, it is of compact size and the path length of the beam inside the device i...

A two-dimensional (2D) diffraction model for the calculation of the diffraction field in 2D space and its applications to terahertz parallel-plate waveguide power splitters are proposed in this paper. Compared with the Huygens-Fresnel principle in three-dimensional (3D) space, the proposed model provides an approximate analytical expression to calculate the diffraction field in 2D space. The di...

We present a digital integral imaging system. A Fresnel lenslet array pattern is written on a phase-only LCoS spatial light modulator device (SLM) to replace the regular analog lenslet array in a conventional integral imaging system. We theoretically analyze the capture part of the proposed system based on Fresnel wave propagation formulation. Because of pixelation and quantization of the lensl...

The generalized Fresnel sine integral Sk(x) and its associated functions Sk+(x) Sk?(x) are defined as locally summable on the real line. integrals have huge applications in physics, specially optics electromaghetics. In many diffraction problems plays an important role. this paper calculated commutative neutrix convolutions of with xr, r = 0,1,2,...
