Abstract

A theoretical study of broadband extraordinary optical transmission in gold plasmonic square nanohole arrays and its application on refractive index sensor

Highlights

  • Extraordinary optical transmission (EOT) was first studied in a thin metallic film by T.W Ebbessen in 1998

  • In order to obtain these EOT observations, we theoretically investigated a thin metallic gold film perforated with square nanoholes arrays both symmetrically and asymmetrically based on the silicon dioxide substrate

  • We considered a simple symmetric square nanohole array (SNA), where all the sizes of
