Energy and information flow in superlensing
E. Fourkal, I. Velchev, A. Smolyakov
In the superlens problem, the presence of the reflected wave plays a critical role in the energy and information transfer from the object to recording device: both incident and ref…
Laser-to-proton energy transfer efficiency in laser-plasma interactions
E. Fourkal, I. Velchev, C-M. Ma
It is shown that the energy of protons accelerated in laser-matter interaction experiments may be significantly increased through the process of splitting the incoming laser pulse…
Resonant transparency of materials with negative permittivity
E. Fourkal, I. Velchev, C-M. Ma +1
It is shown that the transparency of opaque material with negative permittivity exhibits resonant behavior. The resonance occurs as a result of the excitation of the surface waves…
Evanescent wave interference and the total transparency of a warm high-density plasma slab
E. Fourkal, I. Velchev, C-M. Ma +1
It is shown that an overcritical density plasma slab can be totally transparent to a \textit{p}-polarized obliquely incident electromagnetic wave. High transparency is achieved due…
