Abstract
A metamaterial comprises a support medium, such as a planar dielectric substrate and a plurality of resonant circuits supported thereby. At least one resonant circuit is a tunable resonant circuit including a conducting pattern and a tunable material, so that an electromagnetic parameter (such as resonance frequency) may be adjusted using an electrical control signal applied to the tunable material.
