Ultra-Spectrally Selective THz Band Stop Reflector

Technology #11645

Key Points

  • A device that can inhibit the reflectance of electromagnetic radiation in the THz frequency range
  • Enables resonating frequencies (spectral selectivity) in the THz range (0.1-25)
  • May be used to create frequency-selective spectrometry when using both a broadband source and broadband detector

Abstract

The University of Central Florida invention is a device that can inhibit the reflectance of electromagnetic radiation in the THz frequency range. It is characterized by a combination of material and geometric parameters that are unique and tunable—enabling resonating frequencies (spectral selectivity) in the THz range (0.1-25) with narrow channel widths (FWHM) controllable by the thickness and electrical properties of the crystalline material. Spectral filtering is useful in many applications, from fundamental science to spectrometry using lasers and broadband emitters. This device may be integrated with broadband sources or co-integrated with other analytical detection methods (such as chromatography, Fourier transform reflectance spectroscopy).
