Electromagnetic Fields in a Cavity Filled with Some Nonstationary Media

چکیده
Interaction of electromagnetic fields with media that have time varying properties is of significant interest in different applications. Among such phenomena we should mention propagation of electromagnetic pulses in modulated dielectric waveguides, which finds applications in a range of areas including pulse generation, compression, reshaping and filtering, wavelength conversion and terahertz wave generation. Analysis of such phenomena also provides useful insight onto behavior of high speed switches, ultra-short pulse lasers etc. More generally, these problems are of significant importance for understanding of optical communications technology and quantum electronics [6–11]. The problem of interaction of transient electromagnetic fields in a cavity with time-varying filling is the first step in studying non-stationary media. Change in medium parameters significantly

Investigation of Natural Convection in a Vertical Cavity Filled with a Anisotropic Porous Media
In present paper, a numerical analysis for a rectangular cavity filled with a anisotropic porous media has been studied. It is assumed that the horizontal walls are adiabatic and impermeable, while the side walls of the cavity are maintained at constant temperatures and concentrations. The buoyancy force that induced the fluid motion are assumed to be cooperative. In the two extreme cases o...
متن کاملNonclassical phase of the electromagnetic field in a nonstationary dielectric
There has been recently an increased interest in quantum phenomena in nonstationary media. Most of the recent work addresses the possibility of photon generation in simple models of dielectrics and a dielectric cavity with a timevarying index of refraction @1#. In this context methods for producing an appropriately large rate of change of the refractive index have also been anticipated, e.g., i...
متن کامل“Triple M†Effect: A Proposed Mechanism to Explain Increased Dental Amalgam Microleakage after Exposure to Radiofrequency Electromagnetic Radiation
A large body of evidence now indicates that the amount of mercury released from dental amalgam fillings can be significantly accelerated by exposure to radiofrequency electromagnetic fields (RF-EMFs) such as common mobile phones and magnetic resonance imaging (MRI). Studies performed on the increased microleakage of dental amalgam restorations after exposure to RF-EMFs have further supported th...

متن کاملDegree of Polarization of a Twisted Elec- Tromagnetic Gaussian Schell-model Beam in a Gaussian Cavity Filled with Gain Media
Analytical formula for the cross-spectral density matrix of a twisted electromagnetic Gaussian Schell-model (TEGSM) beam propagating through an astigmatic ABCD optical system in gain or absorbing media is derived based on the unified theory of coherence and polarization. Generalized tensor ABCD law in media is derived. As an application example, the evolution properties of the degree of polariz...
