All optical metamaterial circuit board at the nanoscale.
TL;DR: The concept of an optical nanocircuit board, constituted of a layered metamaterial structure with low effective permittivity, over which specific traces that channel the optical displacement current may be carved out, allowing the optical "local connection" among "nonlocal" distant nanoccircuit elements.
Cloaking and invisibility: A review
Romain Fleury,Andrea Alù +1 more
TL;DR: In this article, the state-of-the-art in the science of invisibility for electromagnetic waves, and examine the different available technical concepts and experimental investigations, focusing on the underlying physics and the basic scientific concepts.
Reflectionless sharp bends and corners in waveguides using epsilon-near-zero effects
TL;DR: In this article, the bending features of metamaterials were investigated relative to the counterintuitive resonant effect and it was shown that sharp and narrow bends can be inserted within the propagation channel without causing any sensible reflection or loss and without affecting its tunneling properties.
Three-dimensional nanotransmission lines at optical frequencies: A recipe for broadband negative-refraction optical metamaterials
Andrea Alù,Nader Engheta +1 more
TL;DR: In this paper, the authors apply the optical nanocircuit concepts to design and analyze in detail a 3D plasmonic nanotransmission line network that may act as a relatively broadband negative-refraction metamaterial at infrared and optical frequencies.
Observation of temporal reflection and broadband frequency translation at photonic time interfaces
TL;DR: In this article , a pair of temporal interfaces are combined to demonstrate time-reflection-induced wave interference, realizing the temporal counterpart of a Fabry-Perot cavity, with opportunities for extreme photon manipulation in space and time.
