Abstract :
The phenomenon of negative refraction in a Metamaterial wedge is known to be relatively narrowband. Here, we first experimentally estimate the negative refraction bandwidth of a Metamaterial wedge using a slab and a series of CW measurements. We subsequently measure the RF bandwidth of the Metamaterial wedge using a series of simple QPSK modulated signals. The measured RF bandwidth correlates well with the bandwidth estimate made using the slab and CW measurements.
