Negative Refraction in Plasma and Magnetic Materials

12th International Congress on Artificial Materials for Novel Wave Phenomena, MetaMaterials 2018 -- 27 August 2018 through 1 September 2018 -- -- 142487
The possibility of negative refractive index in plasma and magnetic materials was considered with a new approach. It is shown that simplification of fundamental equations by neglecting losses leads to losing important features about refractive index and therefore, it is expedient to take into consideration imaginary parts of dielectric permittivity and magnetic permeability for an accurate statement of the problem. Also active materials were briefly discussed via new approach. © 2018 IEEE.
