TL;DR: This work applies finite, embedded coordinate transformations to the design of several devices, including a parallel beam shifter and a beam splitter, both of which are reflectionless and exhibit unusual electromagnetic behavior as confirmed by 2D full-wave simulations.

TL;DR: In this article, it was shown that the optical transmission through subwavelength holes in metal films can be enhanced by several orders of magnitude by enabling interaction of the incident light with independent surface plasmon (SP) modes on either side of the film.

TL;DR: In this article, it was shown that moving to a general co-ordinate transformation is equivalent to renormalizing e and μ, which is an huge simplification because now we need only write one computer code in a Cartesian system, and we can use this same code to handle any coordinate system by adjusting the e and µ we feed into the calculation.

TL;DR: In this article, the sensitivity of this subwavelength focus to the slab material properties and periodicity was studied, and the connection to slab surface plasmon modes was made.

TL;DR: The authors showed that materials engineered to have negative permittivity and permeability demonstrate exotic behavior, from a negative refractive index to subwavelength focusing, demonstrating exotic behavior from negative to positive refractive indices.
