Description

Programmable electromagnetic surfaces (PES), also known as reconfigurable intelligent surfaces (RIS), are the enabler of key transformative applications relevant to the US Air Force. A PES generally consists of an array of elements whose reflection coefficient can be adjusted at least in phase, and ideally also in amplitude. Common techniques utilized for phase and amplitude control at lower frequencies cannot be re-utilized at frequencies above 100 GHz. The objective of this research is to design, fabricate, program, and demonstrate non-volatile and wirelessly controlled PES that leverage the hybrid integration of Hafnium Zirconium Oxide (HZO) and graphene and are able to support unique communication and sensing applications at true terahertz frequencies (i.e., 1~THz).
