Three-Dimensional Invisibility Cloak at Optical Wavelengths
TL;DR: A three-dimensional invisibility-cloaking structure operating at optical wavelengths based on transformation optics is designed and realized and uses a woodpile photonic crystal with a tailored polymer filling fraction to hide a bump in a gold reflector.

Superluminal media formed by photonic crystals for transformation optics-based invisibility cloaks
TL;DR: In this paper, an approach to build superluminal medium for transformation optics-based devices, including invisibility cloaks, from photonic crystals was developed. But this medium requires neither material homogenization, nor obtaining the effective parameters with peculiar values and Lorentz's type resonances in rods.
