Unidirectional Curved Surface Plasmon Polariton in a Radially Magnetized System
Samaneh Pakniyat, Alexander H Holmes, George W Hanson
Dynamic manipulation of the surface plasmon polariton (SPP) and wave steering are important in plasmonic applications. In this work, we excite a curved SPP in topological continua…
Chern Invariants of Topological Continua; a Self-Consistent Nonlocal Hydrodynamic Model
Samaneh Pakniyat, S. Ali Hassani Gangaraj, George W Hanson
The bulk-edge correspondence is a fundamental principle of topological wave physics, which states that the difference in gap Chern numbers between the interfaced materials is equal…
Reflectionless Plasmonic Right-Angled Waveguide Bend and Divider Using Graphene and Transformation Optics
Samaneh Pakniyat, Shahrokh Jam, Alireza Yahaghi +1
In this work, a plasmonic right-angled waveguide bend and divider are proposed. Using the Transformation Optics (TO) approach the transformation media of a bend and a T-shaped divi…
Indium Antimonide, constraints on practicality as a magneto-optical platform for topological surface plasmon polaritons
Samaneh Pakniyat, Yi Liang, Yinxiao Xiang +3
Magnetic-field-biased indium antimonide (InSb) is one of the most widely-discussed materials for supporting nonreciprocal surface plasmon polaritons (SPPs), which have recently bee…
Unidirectional and diffractionless surface plasmon-polaritons on three-dimensional nonreciprocal plasmonic platforms
S. Ali Hassani Gangaraj, George W. Hanson, Mario G. Silveirinha +3
Light-matter interactions in conventional nanophotonic structures typically lack directionality. Furthermore, surface waves supported by conventional material substrates do not usu…
Optical torque on a two-level system near a strongly nonreciprocal medium
S. Ali Hassani Gangaraj, Mário G. Silveirinha, George W. Hanson +2
We investigate the quantum optical torque on an atom interacting with an inhomogeneous electromagnetic environment described by the most general linear constitutive relations. The…
