Design Method for Electromagnetic Cloak with Arbitrary Shapes Based on Laplace's Equation [PDF]

open access: yes, 2008
In transformation optics, the space transformation is viewed as the deformation of a material. The permittivity and permeability tensors in the transformed space are found to correlate with the deformation field of the material.

Extraordinary localization of TE-waves at the graphene layer

open access: yes, 2013
The propagation of electromagnetic waves along the surface of a nonlinear dielectric covered by a graphene layer is investigated. The main result is that such a surface can support and stabilize nonlinear transverse electric (TE) plasmon polaritons.

A waveguide metasurface based quasi-far-field transverse-electric superlens

open access: yesOpto-Electronic Advances, 2021
The imaging capability of conventional lenses is mainly limited by the diffraction of light, and the so-called superlens has been developed allowing the recovery of evanescent waves in the focal plane.
