We report the design, fabrication and measurement of a dual-band polarization-independent terahertz reflectarray surface integrated on a silicon reflective substrate. The proposed device opens an important avenue for the integration of tunable elements in terahertz reflectarrays.
We present the experimental demonstration of the first terahertz isolator (working frequency > 1 THz), obtained using the non-reciprocal electromagnetic properties of graphene under magnetostatic bias. The presentation will cover in detail the design, fabrication and measurement of the device. The isolator operated in reflection for circularly polarized waves, showing two bands at 3 and 7.5 terahertz...
We describe the current status of our research on reflectarray antennas operating at terahertz frequencies. We present preliminary measurements of a fixed beam reflectarray operating at 1 THz fabricated on silicon and characterized with a THz time domain system. Secondly, we study theoretically the applicability of novel reconfigurable materials, namely graphene and vanadium dioxide to attain phase...
