A NOVEL TUNABLE ANTENNA AT THZ FREQUEN- CIES USING GRAPHENE ... A beam reconflguration antenna was designed using a switchable high impedance surface (HIS) [11]. In [12], graphene acts as an antenna radiator and has an active resonance frequency based on the concept of surface plasmonic resonance. In this work, a novel tunable antenna using graphene-based AMC is proposed for THz applications.

Applications of the HTS devices based on Josephson junctions have been extended from lower electromagnetic bands (microwave) into mm-wave and terahertz, regions. dual band thermal: Topics by WorldWideScience.org This technique is based on a delicately designed topology of L- and Ku- band microwave filters. The two band-pass responses are generated by a capacitively-loaded square-loop frequency selective surface and an aperture-coupled frequency … dielectric resonator antenna: Topics by WorldWideScience.org On top of the slot there is an air cavity and on top, a small portion of a hemispherical lens. The fractional bandwidth of such antennas is around 10 percent, which is good enough for heterodyne imaging applications.The new geometry makes …
