Average energy required to produce an ion pair, revisited
E. Fourkal, A. Nahum, C. MA +1
The present work is a theoretical/computer simulation study aimed at investigating the dependence of the w value in air on the initial energy of the ionizing electrons. The current…
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…
