Interfacial strong coupling and negative dispersion of propagating polaritons in freestanding oxide membranes
Brayden Lukaskawcez, Shivasheesh Varshney, Sooho Choo +12
Membranes of complex oxides like perovskite SrTiO3 extend the multi-functional promise of oxide electronics into the nanoscale regime of two-dimensional materials. Here we demonstr…
Graphene plasmon-phonon coupled modes at the exceptional point
Sang Hyun Park, Shengxuan Xia, Sang-Hyun Oh +2
Properties of graphene plasmons are greatly affected by their coupling to phonons. While such coupling has been routinely observed in both near-field and far-field graphene spectro…
Anisotropic Acoustic Plasmons in Black Phosphorus
In-Ho Lee, Luis Martin-Moreno, Daniel A. Mohr +3
Recently, it was demonstrated that a graphene/dielectric/metal configuration can support acoustic plasmons, which exhibit extreme plasmon confinement an order of magnitude higher t…
Tunable Graphene Metasurface Reflectarray for Cloaking, Illusion and Focusing
Sudipta Romen Biswas, Cristian E Gutiérrez, Andrei Nemilentsau +4
We present a graphene-based metasurface that can be actively tuned between different regimes of operation, such as anomalous beam steering and focusing, cloaking and illusion optic…
