Extraordinary wavelength reduction in terahertz graphene-cladded photonic crystal slabs
Ian A. D. Williamson, S. Hossein Mousavi, Zheng Wang
Photonic crystal slabs have been widely used in nanophotonics for light confinement, dispersion engineering, nonlinearity enhancement, and other unusual effects arising from their…
Trapping and guiding surface plasmons in curved graphene landscapes
Daria Smirnova, S. Hossein Mousavi, Zheng Wang +2
We demonstrate that graphene placed on top of structured substrates offers a novel approach for trapping and guiding surface plasmons. A monolayer graphene with a spatially varying…
Kinetic inductance driven nanoscale 2D and 3D THz transmission lines
S. Hossein Mousavi, Ian A. D. Williamson, Zheng Wang
We examine the unusual dispersion and attenuation of transverse electromagnetic waves in the few-THz regime on nanoscale graphene and copper transmission lines. Conventionally, suc…
Topologically protected elastic waves in phononic metamaterials
S. Hossein Mousavi, Alexander B. Khanikaev, Zheng Wang
Topological states of quantum matter exhibit unique disorder-immune surface states protected by underlying nontrivial topological invariants of the bulk. Such immunity from backsca…
