Journal ArticleDOI
Atomically thin surface cloak using graphene monolayers.
Pai-Yen Chen,Andrea Alù +1 more
TL;DR: It is shown that an atomically thin graphene monolayer may drastically suppress the scattering of planar and cylindrical objects and, at the same time, preserve moderately broad bandwidth of operation.
Journal ArticleDOI
Giant nonlinear response from plasmonic metasurfaces coupled to intersubband transitions
Jongwon Lee,Mykhailo Tymchenko,Christos Argyropoulos,Pai-Yen Chen,Feng Lu,Frederic Demmerle,Gerhard Boehm,Markus-Christian Amann,Andrea Alù,Mikhail A. Belkin +9 more
TL;DR: The proposed structures can act as ultrathin highly nonlinear optical elements that enable efficient frequency mixing with relaxed phase-matching conditions, ideal for realizing broadband frequency up- and down-conversions, phase conjugation and all-optical control and tunability over a surface.
Journal ArticleDOI
Mantle cloaking using thin patterned metasurfaces
Pai-Yen Chen,Andrea Alù +1 more
TL;DR: In this article, the concept of mantle cloaking is explored, showing that a single, ultrathin, conformal metasurface may drastically suppress the scattering from planar [1D], cylindrical [2D], and/or spherical [3D] objects.
Journal ArticleDOI
Boosting optical nonlinearities in ε-near-zero plasmonic channels
TL;DR: The anomalous transmission properties of zero-permittivity ultranarrow channels are used to boost Kerr nonlinearities and achieve switching and bistable response for moderate optical intensities as mentioned in this paper.
Journal ArticleDOI
Broadening the cloaking bandwidth with non-Foster metasurfaces.
TL;DR: The concept and practical design of broadband, ultrathin cloaks based on non-Foster, negatively capacitive metasurfaces are introduced and it is shown that it is possible to drastically reduce the scattering over a wide frequency range in the microwave regime.
