The propagation of electromagnetic waves trapped within dielectric and magnetic layers is considered. The description within the three-dimensional theory is compared to the simplified analysis in two dimensions. Two distinct media configurations of different topology are dealt with: a plane slab and a ...
We give a brief review of the statistical density operator approach which is adopted for studying the electromagnetic (EM) waves propagating in nonconducting linear media, their dissipation and stability. The approach provides an analytical instrument for studying sensitive and non-invasive measurements,...
We have described an electromagnetic field confined in a cubic cavity filled with a conductive medium from the viewpoint of quantum mechanics; we have also described the field propagating under periodic boundary conditions, and the field having continuous modes, from the viewpoint of quantum mechanics...
An electromagnetic wave in a single mode will be injected into the plasma waveguide from the filled dielectric waveguide. The interaction of the incident wave with interface surface, between two semi-bounded waveguides, will produce new modes for the transmitted waves. It will be shown that the ...
In magnetic fusion devices, radio frequency (rf) waves in the electron cyclotron (EC) and lower hybrid (LH) range of frequencies are being commonly used to modify the plasma current profile. In ITER, EC waves are expected to stabilize the neoclassical tearing mode (NTM) by providing current ...
Marie and Pierre Curie were talented scientists who studied and advanced the many uses of X-rays. Unfortunately, they were not aware of the damaging health consequences of repeated and prolonged exposure to intense radiation, or waves of electromagnetic energy. X-rays are powerful waves of electrom...

It is shown that the effect of a thin lens on a paraxial electromagnetic wave is given by a six-dimensional transformation matrix, constructed out of certain special generators of the Poincaré group. The method of construction guarantees that the free propagation of such waves as well as their...
It is interesting to note that, even if the time-dependence of parameters disappears, the Hamiltonian of an electromagnetic field is time-dependent as long as the conductivity exists7,10. There exist generally accepted approaches for developing the quantum theory of light waves of which the ...
