Negative beam displacements from negative-index photonic metamaterials

Negative beam displacements from negative-index photonic metamaterials.

It is well known that refraction of light at interfaces leads to a beam displacement for oblique incidence of light onto a slab of material. In ray optics and for homogeneous isotropic materials, the sign of this beam displacement is strictly identical to the sign of the refractive index. Our numerical calculations reveal negative beam displacements from state-of-the-art double-fishnet-type pho...

Connected bulk negative index photonic metamaterials.

We show the designs of bulk one- and two-dimensionally isotropic photonic negative index metamaterials working around telecom wavelengths. The designed structures are inherently connected, which makes fabrication by direct laser writing and chemical vapor deposition or other techniques possible.

Negative refractive index metamaterials

a negative index of refraction over a band of microwave frequencies1. This demonstration of a previously unexploited electromagnetic (EM) property proved the importance of engineered materials and has resulted in an extraordinary amount of continued development by scientists working in optics, electromagnetism, physics, engineering, and materials science. Experimental results revealing new phen...
