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…

Harnessing the frequency eigenchannels of ultrafast time-varying media
I. R. Hooper, D. B. Phillips, S. A. R. Horsley
Control over the interaction of waves with ultrafast time-varying materials - those that change on a time-scale commensurate with the wave period - holds much promise for developin…
