Optical Properties of Plasmonic Crystal at Terahertz Frequencies and the Advanced Application

Abstract

We introduce the recent topics concerning the 1D- and 2D- plasmonic crystals, i.e., a wire grid polarizer and a metal mesh device at terahertz frequencies. We show the remarkable increase in polarization characteristics on a freestanding double-layered wire grid polarizer. We also show the performance of metal mesh devices for biosensing application.
