Astronomers place the submillimetre waveband between the far-infrared and microwave wavebands, typically taken to be between a few hundred micrometres and a millimetre.
However, the low spectral resolution over "g" -factor at these wavebands limits the study of paramagnetic centers with comparatively low anisotropic magnetic parameters.
With its narrow field, the visible waveband capability is truly valuable to identify targets in situations where visual contact is required by the rules of engagement.
Recently, he has helped develop a photonic quasicrystal (the quasicrystal analogue of a photonic crystal) for efficiently trapping and manipulating light in selected wavebands.
