Strongly anisotropic waveguide as a nonmagnetic left-handed system
Strongly anisotropic waveguide as a nonmagnetic left-handed system
We develop a new approach to build a material with negative refraction index. In contrast to conventional designs which make use of a resonant behavior to achieve a non-zero magnetic response, our material is intrinsically non-magnetic and relies on an anisotropic dielectric constant to provide a left-handed response in waveguide …
