Resumen
In this communication we report plano-concave
and bi-concave metamaterial lenses based on the close stack of
subwavelegnth hole arrays. Contrary to what is expected from
cut-off holes, an engineered array of holes supports Extraordinary
Transmission. Moreover, the medium formed when those
structures are subwavelength stacked (thus, under metamaterial
condition) behaves as a medium with effe ...

In this communication we report plano-concave
and bi-concave metamaterial lenses based on the close stack of
subwavelegnth hole arrays. Contrary to what is expected from
cut-off holes, an engineered array of holes supports Extraordinary
Transmission. Moreover, the medium formed when those
structures are subwavelength stacked (thus, under metamaterial
condition) behaves as a medium with effective negative index
of refraction, which allows designing new lenses with properties
that were only guessed at not long ago such as perfect imaging,
subdiffraction and free-space matching to name a few. [--]
