Generating phase singularities using surface exciton polaritons in an organic natural hyperbolic material
Philip A. Thomas, William P. Wardley, William L. Barnes
Surface polaritons (SPs) are electromagnetic waves bound to a surface through their interaction with charge carriers in the surface material. Hyperbolic SPs can be supported by opt…

Response to Comment on "Non-Polaritonic Effects in Cavity-Modified Photochemistry": On the Importance of Experimental Details
Philip A. Thomas, William L. Barnes
This note responds to Schwartz and Hutchison's Comment (arXiv:2403.06001) on our article (DOI:10.1002/adma.202309393). We think differences have arisen not in the experimental resu…

Dispersion of backward-propagating waves in a surface defect on a 3D photonic band gap crystal
Timon J. Vreman, Melissa J. Goodwin, Lars J. Corbijn van Willenswaard +3
We experimentally study the dispersion relation of waves in a two-dimensional (2D) defect layer with periodic nanopores that sits on a three-dimensional (3D) photonic band gap crys…
