Analysis of terahertz wave penetration capacity to 2D conductive cylinder coated with steady-state parabolic distribution plasma media

Results in Physics, 2021
Terahertz waves have long been considered as the most efficient of many solutions to solve the blackout problem for the reason that terahertz waves have much stronger penetration than microwaves.

Impact of nonlinear loss on Stimulated Brillouin Scattering

, 2015
We study the impact of two-photon absorption (2PA) and fifth-order nonlinear loss such as 2PA-induced free-carrier absorption in semiconductors on the performance of Stimulated Brillouin Scattering devices.

Band structure effects for dripped neutrons in neutron star crust

, 2004
The outer layers of a neutron star are supposed to be formed of a solid Coulomb lattice of neutron rich nuclei. At densities above neutron drip density (about one thousandth of nuclear saturation density), this lattice is immersed in a neutron fluid ...
