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…
Intelligent Metasurfaces with Continuously Tunable Local Surface Impedance for Multiple Reconfigurable Functions
Fu Liu, Odysseas Tsilipakos, Alexandros Pitilakis +7
Electromagnetic metasurfaces can be characterized as intelligent if they are able to perform multiple tunable functions, with the desired response being controlled by a computer in…
Investigation of broadband terahertz generation from metasurface
Ming Fang, Kaikun Niu, Zhiaxiang Huang +4
The nonlinear metamaterials have been shown to provide nonlinear properties with high nonlinear conversion efficiency and in a myriad of light manipulation. Here we study terahertz…
Electronic, optical and transport properties of van der Waals Transition-metal Dichalcogenides Heterostructures: A First-principle Study
Ke Xu, Yuanfeng Xu, Hao Zhang +8
Two-dimensional (2D) transition-metal dichalcogenide (TMD) MX (M = Mo, W; X= S, Se, Te) possess unique properties and novel applications. In this work, we perform first-princip…
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…
