Electromagnetic plane waves with negative phase velocity in charged black strings

Nuclei, Particles, Fields, Gravitation, and Astrophysics

Abstract

We investigate the propagation regions of electromagnetic plane waves with negative phase velocity in the ergosphere of static charged black strings. For such a propagation, some conditions for negative phase velocity are established that depend on the metric components and the choice of the octant. We conclude that these conditions remain unaffected by the negative values of the cosmological constant.
