Modeling of radiation characteristics of semitransparent media containing particles or bubbles in the independent scattering limit is examined. The existing radiative properties models of a single particle in an absorbing medium using the approaches based on (1) the classical Mie theory neglecting absorption by the matrix, (2) the far field approximation, and (3) the near field approximation ar...

In the decoupling limit of a non-minimal Higgs sector, the lightest CP-even Higgs boson (h) is indistinguishable from the Standard Model (SM) Higgs boson. In the two-Higgs-doublet sector of the MSSM, the approach to the decoupling limit (for mA ≫ mZ) persists, even in the presence of potentially large (tanβ-enhanced) radiative corrections to the hbb̄ coupling. Radiative corrections can also gene...

We theoretically demonstrate a near-field radiative thermal switch based on thermally excited surface plasmons in graphene resonators. The high tunability of graphene enables substantial modulation of near-field radiative heat transfer, which, when combined with the use of resonant structures, overcomes the intrinsically broadband nature of thermal radiation. In canonical geometries, we use non...

In this paper vibration of ferromagnetic rectangular plates which are subjected to an inclined magnetic field is investigated based on classical plate theory and Maxwell equations. Levy type solution and Finite element method using Comsol software are used to obtain the frequency of the plate subjected to different boundary conditions, good agreements is obtained when computed results are compa...

We explore the importance of magnetic-field-oriented thermal conduction in the interaction of supernova remnant (SNR) shocks with radiative gas clouds and in determining the mass and energy exchange between the clouds and the hot surrounding medium. We perform 2.5D MHD simulations of a shock impacting on an isolated gas cloud, including anisotropic thermal conduction and radiative cooling; we c...

In this paper we employ finite-difference time-domain (FDTD) simulations to study the resonant modes in rectangular dielectric resonators (DRs). Three-dimensional field patterns for these modes are derived, and the modes are represented by combinations of equivalent electric and magnetic dipoles. The possibility of exciting TM-type modes in rectangular DRs is demonstrated. © 2003 Wiley Periodic...

We present a revision of the results obtained by Alecian & Stift (2002) on the amplification, by Zeeman splitting in strong stellar magnetic fields, of radiative accelerations of chemical elements. These results had been obtained for blended spectra and were based on the Zeeman Feautrier method as presented by Rees et al. (1989) which however requires perfect symmetry of the line profiles. The ...
