Effects due to generation of negative frequencies during temporal diffraction
E. Hendry, C. M. Hooper, W. P. Wardley +1
Temporal diffraction from rapidly time-modulated materials can generate new frequency components not present in an incident wave. In such an experiment, the spectral extent of thes…
Finding passive, reciprocal metasurfaces for arbitrary wave transformations
K. O. Arnold, C. Hooper, J. Smith +4
We give a general design method for finding the passive, reciprocal surface impedance tensor required to enact any wave transformation. We do this through characterising the surfac…
Space-Time Optical Diffraction from Synthetic Motion
A. C. Harwood, S. Vezzoli, T. V. Raziman +7
The interaction of light with objects and media moving at relativistic and superluminal speeds enables unconventional phenomena such as Fresnel drag, Hawking radiation, and light a…
Optimizing achromaticity in metalenses, and development of a layered thin-film metalens
Calvin M. Hooper, Sarah E. Bohndiek, Calum Williams
Metalenses are ultrathin optical devices designed to replicate behavior of conventional refractive lenses, or lens arrays, utilizing nanoscale resonant structures to redirect incid…
