Plasmonic Devices for Electromagnetic Wave Concentration
Abstract: The EOT effect is enhanced by the concentration of EM waves. We explored optical transmission through arrays of nanohole pairs and found that the EOT effect through subwavelength nanoholes is enhanced by the confinement of electric field, and that the transmission is substantially higher than predicted. The optical transmission capabilities of arrays of isolated nanohole pairs and bridging nanohole pairs in gold with various geometrical configurations were explored and investigated …
