Metamaterial tuning by manipulation of near-field interaction
(American Physical Society, 2010)
We analyze the near-field interaction between the resonant subwavelength elements of a metamaterial and present a method to calculate the electric and magnetic interaction coefficients. We show that by adjusting the relative ...

Study of extraordinary transmission in a circular waveguide system
(Institute of Electrical and Electronics Engineers, 2010)
Extraordinary transmission through periodic distributions of sub-wavelength holes made in opaque screens has been demonstrated and exhaustively studied along the last decade. More recently, extraordinary transmission has ...

Realistic metamaterial lenses: Limitations imposed by discrete structure
(American Physical Society, 2010)
We study the peculiarities of a metamaterial "superlens," caused by its discrete structure and finite size. We show that precise modeling of the lens provides remarkable distinctions from continuous medium approximation. ...

Analytical theory of extraordinary optical transmission through realistic metallic screens
(Optical Society of America, 2010)
An analytical theory of extraordinary optical transmission (EOT) through realistic metallic screens perforated by a periodic array of subwavelength holes is presented. The theory is based on our previous work on EOT ...
