Order Maintenance in Worst-Case Constant Time, Verified
Denis Firsov
Order maintenance asks for a data structure that keeps a sequence of elements under insertions and deletions and tells which of two elements comes first. We give an algorithm, asse…

Enhanced THz third-harmonic generation in graphene via hot-carriers in a topological cavity
Spyros Doukas, Ioannis Katsantonis, Thomas Koschny +2
Graphene is a promising material for nonlinear THz applications owing to its high third-order susceptibility and tunable optical properties. Its strong nonlinear response, driven b…

Multispectral Polarization-Insensitive Graphene/Silicon Guided Mode Resonance Active Metasurfaces
Prateeksha Sharma, Dor Oz, Eleftheria Lampadariou +3
We investigate advanced CMOS-compatible Graphene/Silicon active metasurfaces based on guided-mode resonance filters. The simulated results show a high extinction ratio (>25 dB), na…
