J. Bravo-Abad, A.I. Fernandez-Dominguez, F.J. Garcia-Vidal, L., Martin-Moreno
TL;DR
This paper presents a theoretical framework explaining how quasiperiodic arrays of subwavelength holes enable extraordinary light transmission by selecting specific surface electromagnetic modes due to their long-range order.
Contribution
It introduces a formalism applicable in real and k-space to elucidate the physical mechanism behind extraordinary transmission in quasiperiodic hole arrays.
Findings
Long-range order in quasiperiodic arrays selects specific wavevectors.
Surface electromagnetic modes facilitate efficient light transmission.
The formalism unifies real and k-space analyses.
Abstract
By using a theoretical formalism able to work in both real and k-spaces, the physical origin of the phenomenon of extraordinary transmission of light through quasi-periodic arrays of holes is revealed. Long-range order present in a quasiperiodic array selects the wavevector(s) of the surface electromagnetic mode(s) that allows an efficient transmission of light through subwavelength holes.
