Abstract :
We demonstrate a proto-type of a new class of THz metamaterial modulators employing metallic frequency selective surfaces (FSS) in conjunction with patterned graphene placed within the near field of FSS. Owing to the field enhancement in the near field, this device structure can potentially circumvent the limited conductivity swing in large area graphene as well as promise high modulation depth, low insertion loss and high operation speed.
