چکیده

We present a numerical integration scheme for the propagation of particles/rays within continuous, inhomogeneous media, represented as discrete scalar fields. Our method aims at the calculation of energy distribution, where the initial energy is evenly distributed over a large number of particles, which are traced through the medium. While traversing the particles interact with the medium by means of absorption, reflection and refraction. To calculate these paths, we construct a numerical integration formula based on refraction and reflection laws given for rigid material boundaries. Numerical examples show that our method correctly traces particles/rays within e.g. curved optical fibers with a circular cross-section density.

A Higher Order B-Splines 1-D Finite Element Analysis of Lossy Dispersive Inhomogeneous Planar Layers

In this paper we propose an accurate and fast numerical method to obtain scattering fields from lossy dispersive inhomogeneous planar layers for both TE and TM polarizations. A new method is introduced to analyze lossy Inhomogeneous Planar Layers. In this method by applying spline based Galerkin’s method of moment to scalar wave equation and imposing boundary conditions we obtain reflection and...

Exact solution for scalar field collapse.

We give an exact spherically symmetric solution for the Einstein-scalar field system. The solution may be interpreted as an inhomogeneous dynamical scalar field cosmology. The spacetime has a timelike conformal Killing vector field and is asymptotically conformally flat. It also has black or white hole-like regions containing trapped surfaces. We describe the properties of the apparent horizon ...

Auxiliary Potentials In Chiral Media

In the present paper, the expressions for scalar and vector potentials in lossless isotropic chiral media are analyzed. Propagating eigenvalues of these potentials are then obtained. Furthermore by decomposition of sources and fields in a chiral medium, we introduce the auxiliary right-and left-handed potentials and find the associated fields. These potentials are used to solve the problem of a...

Black hole entropy without brick walls.

We present evidence which con rms a suggestion by Susskind and Uglum regarding black hole entropy. Using a Pauli-Villars regulator, we nd that 't Hooft's approach to evaluating black hole entropy through a statistical-mechanical counting of states for a scalar eld propagating outside the event horizon yields precisely the one-loop renormalization of the standard Bekenstein-Hawking formula, S = ...

Singlet scalar dark matter in noncommutative space

In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered,  but our information about  the nature of dark matter is still limited. There are such particle candidates as  scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...
