Fresnel reflection coefficients in the Fourier domain for a planar surface in uniform motion parallel to its interface
Stéphane Azar, Sebastian Golat, Francisco J. Rodríguez-Fortuño
The optical reflection coefficient of a dielectric medium moving uniformly in the plane spanned by its surface is rigorously calculated using classical electrodynamics and special…

Spectrum of Primordial Gravitational Waves in Presence of a Cosmic String
S. Azar Ag Galeh, A. M. Abbassi, M. H. Abbassi
In this paper we consider an inflating universe with long straight cosmic string along z-axis. We show that the effect of cosmic string can be taken as a perturbation on the backgr…
