Abstract :
We demonstrate here, for the first time, the construction of artificial materials, which theoretically possess two separate pass-bands utilizing the difference between positive and negative refraction in the terahertz frequency regime. Experimental testing of these devices is currently being undertaken using both broadband pulsed sources and narrow frequency quantum cascade lasers.
