Ultrafast modulation in a THz graphene-based flat absorber through negative photoconductivity
Anna C. Tasolamprou, Anastasios D. Koulouklidis, Christina Daskalaki +9
We present the experimental and theoretical study of an ultrafast graphene based thin film absorption modulator for operation in the THz regime. The flat modulator is composed of a…
Wavefront manipulation based of the excitation of bound states in dielectric photonic crystals and bilayer metasurfaces
Anna C. Tasolamprou, Maria Kafesaki, Thomas Koschny +1
We present the study of bound surface modes sustained at the termination of truncated bulk dielectric photonic crystals and isolated metasurfaces of dielectric meta-atoms. We discu…
The Software-Defined Metasurfaces Concept and Electromagnetic Aspects
Anna C. Tasolamprou, Alexandros Pitilakis, Odysseas Tsilipakos +17
We present the concept and electromagnetic aspects of HyperSurFaces (HSFs), artificial, ultrathin structures with software controlled electromagnetic properties. The HSFs key unit…
Exploration of Intercell Wireless Millimeter-Wave Communication in the Landscape of Intelligent Metasurfaces
Anna C. Tasolamprou, Alexandros Pitilakis, Sergi Abadal +19
Software-defined metasurfaces are electromagnetically ultra-thin, artificial components that can provide engineered and externally controllable functionalities. The control over th…
Electromagnetic Aspects of Practical Approaches to Realization of Intelligent Metasurfaces
Fu Liu, Odysseas Tsilipakos, Xuchen Wang +9
We thoroughly investigate the electromagnetic response of intelligent functional metasurfaces. We study two distinct designs operating at different frequency regimes, namely, a swi…
Metasurfaces with Interleaved Electric and Magnetic Resonances for Broadband Arbitrary Group Delay in Reflection
Odysseas Tsilipakos, Thomas Koschny, Costas M. Soukoulis
Metasurfaces impart phase discontinuities on impinging electromagnetic waves that are typically limited to 0-2. Here, we show that they can break free from this limitation and s…
