THz transmission investigation of composed rectangular hole array
|
Abstract:
An investigation of the mechanism of extraordinary transmission through metal hole array at THz range was presented. The experiments and simulations verified that the metal film perforated with rectangular arrays had a peak which related with the length of the rectangular. Furthermore, by composing rectangular holes with different length to form an array, the transmission spectra exhibit two individual peaks or a broaden peak. This composed array has potential applications in THz filter, polarizer, and reflector.
