Polarization-independent Metamaterial with Unnaturally High Refractive Index in the Terahertz Region.

Z Liu, S **ao - PIERS Proceedings, 2014 - search.ebscohost.com
Refractive index is the most important property of material in optics and most naturally
existing transparent materials possess small positive indices of refraction. With the progress …
