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...

A single-layer waveguide slot array antenna of low cost and high performance for a millimetre-wave wireless communication system at 38 GHz frequency band is presented. The waveguide slots and diaphragms are located together on the cover plate of the antenna, which makes the antenna cost effective and highly efficient. Measurements show a cross-polarisation level below 26 dB and an efficiency le...

By using the quantum hydrodynamic and Maxwell equations, we derive the generalized nonlinear electron magnetohydrodynamic, the generalized nonlinear Hall-MHD HMHD , and the generalized nonlinear dust HMHD equations in a self-gravitating dense magnetoplasma. Our nonlinear equations include the self-gravitating, the electromagnetic, the quantum statistical electron pressure, as well as the quantu...

The problem of reduction of the wave packet of a relativistic charged particle by emission of a photon is studied with help of the path integral approach. A general expression for arbitrary order correlation function of the electromagnetic field is obtained. As a specific example an ultrarelativistic electron circulating in a storage ring is considered. It is shown that the longitudinal width o...

BACKGROUND Animal vision spans a great range of complexity, with systems evolving to detect variations in light intensity, distribution, colour, and polarisation. Polarisation vision systems studied to date detect one to four channels of linear polarisation, combining them in opponent pairs to provide intensity-independent operation. Circular polarisation vision has never been seen, and is wide...

Abstract. Radio wave absorption in the ionosphere is a function of electron density, collision frequency, radio polarisation, magnetic field and frequency. Several studies have used multi-frequency measurements cosmic noise to determine density profiles. Using framework statistical inverse problems, we investigated if an altitude profile can be determined by using multi-frequency, dual-polarisa...

The nonreciprocal propagation of electromagnetic waves in ionized gaseous media is discussed, and experimental observations are reported in this paper. The classical Faraday experiment in the optics of anisotropic media has suggested an analogous phenomenon at microwave frequencies. The anisotropic behavior of the free electron gas which is immersed in a magnetic field and subjected to an incid...
