Equivalence of reflection paths of light and Feynman paths in stacked metasurfaces
Jan Sperrhake, Matthias Falkner, Stefan Fasold +2
We show the existence of virtual polarization states during the interaction of modes in metasurface stacks. In support of our findings we experimentally realize a metasurface stack…

Characterization of a circular optical nanoantenna by nonlinear photoemission electron microscopy
Thomas Kaiser, Matthias Falkner, Jing Qi +5
We report on the investigation of an advanced circular plasmonic nanoantenna under ultrafast excitation using nonlinear photoemission electron microscopy (PEEM) under near-normal i…
