Negative refraction in natural ferromagnetic metals
Negative refraction natural ferromagnetic metals

It is generally believed that Veselago’s criterion for negative refraction cannot be fulfilled in natural materials. However, considering imaginary parts of the permittivity (") and permeability(μ) an...
Low-loss negative refraction by laser induced magneto-electric cross-coupling
Low-loss negative refraction laser magneto-electric cross-coupling

We discuss the feasibility of negative refraction with reduced absorption in coherently driven atomic media. Coherent coupling of an electric and a magnetic dipole transition by laser fields induces m...
