Abstract :
We show how a photonic crystal prism can be used to filter a broadband terahertz beam using the properties of negative and positive refraction. Different components of a broadband beam incident on the structure may be positively or negatively refracted, depending upon its frequency. Therefore, the structure can be used as an effective spectral filter of THz radiation.
