The elastic wavefield generated by a point source of tractions acting on the surface of a transversely isotropic half-space is studied. The symmetry axis of the solid is oriented arbitrarily with ...

In work that provides insights for several areas of wave physics -- Maxwell electromagnetism, topological quantum states, and plasmonics/metamaterials -- scientists showed that the well-known surface ...

An interface between media with different helicities (red and blue curly arrows) supports zero-helicity linearly polarized surface modes (green arrow). (Credit: Konstantin Bliokh) Maxwell’s ...
