SURFACE ELECTROMAGNETIC WAVES IN A GAP BETWEEN TWO LEFT-HANDED MATERIALS

open access: yesEast European Journal of Physics, 2018
The slow surface electromagnetic waves that propagate along the planar waveguide structure that contains two identical isotropic left-handed material with the vacuum (or air) gap has been considered.

Wide-angle microwave absorption performance of polyurethane foams combined with cross-shaped metamaterial absorber

open access: yesResults in Physics, 2018
A cross-shaped metamaterial absorber (CSMMA) has been introduced to integrate with two-layered polyurethane foam absorbers (PUFAs). By incorporating with CSMMA, microwave absorptive performance of the proposed PUFAs in 8–18 GHz has been remarkably ...

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.
