A novel design of millimeter-wave antennas integrated with a high-impedance surface (HIS) reflector is presented within the particular context of 3D heterogeneous integration on silicon interposer an its specific requirements. Then, the design steps of a 60-GHz folded dipole antenna for short-range communications are detailed. Simulation and measurement results show promising performances in terms...
Graphene has become an outstanding material for revolutionary wireless applications in the microwave and terahertz/infrared frequency ranges. Due to its unique physical characteristics, a family of completely new devices can be developed by exploiting graphene's behaviour as High Impedance Surface (HIS) or highly-Reactive Impedance Surface (RIS). In this paper we theoretically investigate first a...
This paper presents a generalization of the Oliner's method used to investigate the guided modes supported by a Sinusoidally-Modulated Surface Reactance (SM-SR). In its original paper, Oliner applied the procedure to the case of a scalar and impenetrable impedance sheet in free space; in this work, this approach has been extended to find the guided mode configurations (both leaky and surface waves)...
