A 28-GHz Varactor-Based RIS With Continuous Phase Control: From Unit-Cell Modeling to Programmable Wavefront Control and Synthesis
Spandan Manna, Florian Reher, Karim El Isa +2
This paper presents a 28 GHz varactor-based reconfigurable intelligent surface (RIS) platform with continuous phase control and establishes a unified device-to-system validation fr…
Theory of Seamless-Scanning Periodic Leaky-Wave Antennas based on -Symmetry with Time to Space Mapping
Amar Al-Bassam, Simon Otto, Dirk Heberling +1
Periodic Leaky-Wave Antennas (P-LWA) offer highly directive and space-scanning radiation. Unfortunately, they have been plagued by the ``broadside issue'', characterized by a degra…
Exceptional Point Perspective of Periodic Leaky-Wave Antennas
Amar Al-Bassam, Dirk Heberling, Christophe Caloz
Over the past decade, the issue of gain degradation at broadside in periodic leaky-wave antennas (P-LWAs) has been resolved, using a circuit modeling approach, by introducing prope…
