Abstract :
Metamaterials are engineered materials which offer superb electromagnetic performance over naturally occurring materials, and offer great potential to construct novel devices operating in the terahertz frequency regime. Here we experimentally demonstrate metamaterial narrow band filters, perfect absorbing elements for THz imaging, and ultra-fast THz switches. Experiments are supplanted with simulation and theory, thus verifying high performance.
