Veselago materials: what is possible and impossible about the dispersion of the constitutive parameters / | |
Autor: | Tretyakov, S. A. |
Tema(s): | |
Resumen: | Basic physical limitations on the material constitutive parameters of artificial passive materials with negative real parts of the effective parameters are reviewed. It is shown that field solutions in hypothetical materials with negative and nondispersive parameters are unstable. The energy density and field solutions in active metamaterials with nondispersive negative parameters are also considered |
