NSWCDD

An electromagnetic reflector for reflecting an electromagnetic signal is provided based on meta-surface phase control using photo-capacitive materials, varactors or other tuning means. The shape of the metamaterial unit cell enhances the resonance and phase shift. The reflector includes first and second cells having respective first and second phase states, along with a switch for selecting between the first and second cells.
