A covariant criterion for the emission of Cherenkov radiation in the field of a non-linear gravitational wave is considered in the framework of exact integrable models of particle dynamics and electromagnetic wave propagation. It is shown that vacuum interacting with curvature can give rise to Cherenkov radiation. The conically shaped spatial distribution of radiation is derived and its basic p...

We consider the wave and ray dynamics of an electromagnetic field in a parabolic dome microcavity. The structure of the fundamental s wave involves a main lobe in which the electromagnetic field is confined around the focal point in an effective volume of the order of a cubic wavelength, while modes with finite angular momentum have a structure that avoids the focal area and have correspondingl...

The relativistic motion of an electron is calculated in the combined fields of a transverse helical wiggler field (axial wavelength = X0 27/k 0) and constant-amplitude, circularly polarized primary electromagnetic wave (6B , ,k) propagating in the z-direction. For particle velocity near the beat wave phase velocity w/(k + k0) of the primary wave, it is shown that the presence of a second, moder...

The Aharonov-Bohm effect was conclusively established by a series of our electron interference experiments, with the help of some advanced techniques, such as coherent field-emission electron beams and microlithography. Using this fundamental principle behind the interaction of an electron wave with electromagnetic fields, new observation techniques were developed to directly observe microscopi...

voltages and currents are induced into electronic circuit boards as electromagnetic waves are radiated on them. the strength of induction depends on the wavefront and the circuit board characteristics. in this paper, by solving maxwell’s equations using fdtd method and then by extending it by three dimensional simulation using the gpml criteria for boundary conditions and tf/sf technique, effec...

Here, we report the fabrication of a graphene-based Bragg grating (one-dimensional photonic crystal) and experimentally demonstrate the excitation of surface electromagnetic waves in the periodic structure using prism coupling technique. Surface electromagnetic waves are non-radiative electromagnetic modes that appear on the surface of semi-infinite 1D photonic crystal. In order to fabricate th...
