Impact of Surface Roughness on Light Absorption
V. Gareyan, Zh. Gevorkian
We study oblique incident light absorption in opaque media with rough surfaces. An analytical approach with modified boundary conditions taking into account the surface roughness i…
Light absorption by weakly rough metal surfaces
Zhyrair S. Gevorkian, Ludvig S. Petrosyan, Tigran V. Shahbazyan
We study light absorption by weakly rough metal surfaces with the roughness amplitude and correlation length smaller than the skin depth in metal. We develop a systematic perturbat…
Universal Hall conductivity in graphene Maxwell fish-eye quantum dot
Zhyrair Gevorkian
Graphene quantum dot with Maxwell fish eye potential energy profile is studied. A quasiclassical approximation is used given that potential energy is a slowly varying function of c…
Maxwell fish eye for polarized light
Mher Davtyan, Zhyrair Gevorkian, Armen Nersessian
We consider the propagation of polarized light in the medium with Maxwell fish eye refraction index profile. We show that polarization violates the additional symmetries of medium,…
Discrete spectrum Radiation from a charged particle moving in a medium with Maxwell fish eye refraction index profile
Zhyrair Gevorkian, Mher Davtyan
Radiation from a charged particle moving in a medium with Maxwell fish eye refraction index profile is considered. It is shown that the radiation spectrum has a discrete character.…
Extended symmetries in geometrical optics
Zhyrair Gevorkian, Mher Davtyan, Armen Nersessian
We examine additional symmetries of specific refraction index profiles that are used in the well-known phenomena of perfect imaging and cloaking.In the considered cases, the transl…
