Transition radiation is a fundamental process of light emission and occurs whenever charged particle moves across an inhomogeneous region. One feature transition that it can create at arbitrary frequency under any velocity. Therefore, significant importance to both science practical applications. In this paper, we provide brief historical review its recent development. Moreover, pay special att...

We report on the theoretical calculations considering collinear electromagnetic radiation at the propagation of an optical pulse through a slab of nonlinear material. Calculated waveforms of the radiated field fit well to the experimental dependencies showing the remarkable similarities between the radiation at nonlinear wave interaction and the radiation phenomena of moving external charges, s...

2014 We report the first observation of a strong resonance due to surface plasmons in the transition radiation emitted by films of aluminium deposited on quartz prisms and bombarded with 20 keV electrons. Measurements of the reflectivity of p-polarized light on the same systems show the characteristic attenuated total reflection dip. The correlation of both results and a theoretical analysis al...

Theoretical studies [1-3] have shown that the relativistic subpicosecond electron bunches produced by high-brightness rf photoinjectors can be used to generate coherent synchrotron radiation in a free-electron maser (FEM). Furthermore, in a waveguide structure, the group velocity of the radiation can be matched to the axial bunch velocity in the helical wiggler, thus minimizing slippage in the ...
