negative refractive index, dispersive material, Cherenkov radiationAbstract
The spectrum of Cherenkov‘s optical radiation generated by an anisotropic group of electrons passing through a dispersive tridimensional metamaterial was studied numerically. Such dispersive material was described by Drude model. In this approach, metamaterial parameters are fixed. The frequency spectrum of the system internal excitations generated by the passage of the particle at a rate greater than the speed of light in the medium, were well defined as a result of numerical simulation.
