Chiral metamaterials with PT symmetry and beyond
Sotiris Droulias, Ioannis Katsantonis, Maria Kafesaki +2
Optical systems with gain and loss that respect Parity-Time (PT) symmetry can have real eigenvalues despite their non-Hermitian character. Chiral systems impose circularly polarize…
Intercell Wireless Communication in Software-defined Metasurfaces
Anna C. Tasolamprou, Mohammad Sajjad Mirmoosa, Odysseas Tsilipakos +11
Tunable metasurfaces are ultra-thin, artificial electromagnetic components that provide engineered and externally adjustable functionalities. The programmable metasurface, the Hype…
Programmable Metasurfaces: State of the Art and Prospects
Fu Liu, Alexandros Pitilakis, Mohammad Sajjad Mirmoosa +12
Metasurfaces, ultrathin and planar electromagnetic devices with sub-wavelength unit cells, have recently attracted enormous attention for their powerful control over electromagneti…
