A synthetic approach to some electromagnetic wave phenomena

نویسنده

  • J D Lawson
چکیده

The properties of plane electromagnetic waves in free space, and evanescent waves which can exist near planar boundaries are discussed in detail, and their physical characteristics compared. The discussion is then generalised to other configurations, and with the help of Fourier synthesis several problems are considered from a unified physical viewpoint. Topics covered include particle accelerators, antennas, diffraction gratings, the radiation from curved surface guides, from atoms, from electrons moving in curved paths and Cherenkov radiation.

شبیه‌سازی ذره‌ای شتاب دادن الکترون‌ها در پلاسمای کم چگال

One of the interesting Laser-Plasma phenomena, when the laser power is high and ultra intense, is the generation of large amplitude plasma waves (Wakefield) and electron acceleration. An intense electromagnetic laser pulse can create plasma oscillations through the action of the nonlinear pondermotive force. electrons trapped in the wake can be accelerated to high energies, more than 1 TW. Of t...

A Review of Low Frequency Electromagnetic Wave Phenomena Related to Tropospheric-Ionospheric Coupling Mechanisms

Investigation of coupling mechanisms between the troposphere and the ionosphere requires a multidisciplinary approach involving several branches of atmospheric sciences, from meteorology, atmospheric chemistry, and fulminology to aeronomy, plasma physics, and space weather. In this work, we review low frequency electromagnetic wave propagation in the Earthionosphere cavity from a troposphere-io...

Review and Assessment of Electromagnetic Wave Propagation in Sand and Dust Storms at Microwave and Millimeter Wave Bands — Part I

Electromagnetic wave propagation in arid and semi-arid regions is influenced by sand and dust storms. Meagre information has hitherto been reported as to the effect of storms on telecommunication systems operating in such regions. This paper presents a survey of current understanding of the wave propagation during storms. In this first part of the review—Part I, detailed parametric assessment o...

Simulation of Surface Plasmon Excitation in a Plasmonic Nano-Wire Using Surface Integral Equations

In this paper, scattering of a plane and monochromatic electromagnetic wave from a nano-wire is simulated using surface integral equations. First, integral equationsgoverning unknown fields on the surface is obtained based on Stratton-Cho surface integral equations. Then, the interaction of the wave with a non-plasmonic as well as a palsmonic nano-wire is considered. It is shown that in scatter...
