New absorbing boundary conditions and analytical model for multilayered mushroom-type metamaterials: Applications to wideband absorbers
(Institute of Electrical and Electronics Engineers, 2012)
An analytical model is presented for the analysis of multilayer wire media loaded with 2-D arrays of thin material terminations, characterized in general by a complex surface conductivity. This includes the cases of ...

Enhanced transmission with a graphene-dielectric microstructure at low-terahertz frequencies
(American Physical Society, 2012)
Here, we report on the transmissivity of electromagnetic waves through a stack of monolayer graphene sheets separated by dielectric slabs at low-terahertz frequencies. It is observed that the multilayer structure possesses ...

Excitation of Discrete and Continuous Spectrum in Subdiffraction Wire-Medium Type Lenses
(Institute of Electrical and Electronics Engineers, 2016)
Subwavelength imaging of the near field of a magnetic line-source excitation is studied for several wire-medium (WM) lens topologies using complex-plane analysis of the radiation integral. Nonlocal homogenization is used ...

Dual capacitive-inductive nature of periodic graphene patches: Transmission characteristics at low-terahertz frequencies
(American Physical Society, 2013)
We report on the dual nature (capacitive and inductive) of the surface impedance of periodic graphene patches at low-terahertz frequencies. The transmission spectra of a graphene-dielectric stack shows that patterned ...
