Spin-Type Photonic Topological Insulators on a Rhombic Lattice
Robert J. Davis, Daniel F. Sievenpiper
A simplified model of a metallic spin-type photonic topological insulator on a rhombic lattice is presented and analyzed. Instead of the more commonly used hexagonal unit cells, a…

Helical Phononic Modes Induced by a Screw Dislocation
Yun Zhou, Robert Davis, Li Chen +3
In this study, we investigate a one-dimensional (1D) unidirectional phononic waveguide embedded within a three-dimensional (3D) hexagonal close-packed phononic crystal, achieved by…
