Although full wave electromagnetic systems are large and cumbersome to solve, typically only a few parameters, such as inpul impedance, S parameters, and far field pattern, are needed by' the designer or analyst. A reduced order modeling of these parameters is therefore an imt)ortant consideration in minimizing the CPU requirements. The Asymptotic Waveform Evaluation(AWE) method is one approach...

The Maxwell theory on non-commutative spaces has been considered. The non-linear equations of electromagnetic fields on non-commutative spaces were obtained in the compact spin-tensor (quater-nion) form. It was shown that the plane electromagnetic wave is the solution of the system of non-linear wave equations of the second order for the electric and magnetic induction fields. We have found the...

We calculate the optically thin synchrotron emission of fast electrons and positrons in a spiral stationary magnetic field and a radial electric field of a rotating relativistic strongly magnetized force–free jet consisting of electron-positron pair plasma. The magnetic field has a helical structure with a uniform axial component and a toroidal component that is maximal inside the jet and decre...

In this paper, the scattering of a plane monochromatic electromagnetic wave from a nanowire with circular cross-section in the transverse electric (TE) mode is simulated using the well-known Stratton-Chu surface integral equations. For an ordinary dielectric nanowire the refraction phenomenon is nicely simulated. In the case of a plasmonic nanowire no sign of surface plasmon excitation and prop...

We present the application to transmission line systems of a new theory of the optical theorem that describes the energy budget of electromagnetic scattering in lossless wave propagation media. The insight gained by exploring this, simplest of the electromagnetic wave propagation systems from the point of view of the optical theorem, is important for understanding power budget of electromagneti...

The Electromagnetic Time Reversal (TR) technique is based on the time invariance property of electromagnetic waves. For every forward electromagnetic wave, there exist a back propagating wave which follows the same path. If the medium has less loss and is inhomogeneous, then TR provides better crossrange resolution. The purpose of this paper is to showcase the improved properties of TR and its ...

We study the electromagnetic field equations on an arbitrary quantum curved background in the semiclassical approximation of Loop QuantumGravity. The effective interaction hamiltonian for the Maxwell and gravitational fields is obtained and the corresponding field equations, which can be expressed as a modified wave equation for the Maxwell potential, are derived. We use these results to analyz...
