    Photogeneration of significant electrical voltages observed in plasmonic metasurfaces is promising for applications in plasmon-based electronics and plasmonic sensors with compact electrical detection. In order to better understand the role of the surface geometry, we study photoinduced electrical effects in profile-modulated plasmonic surfaces. Photoinduced voltages in strongly modulated plasmonic surfaces demonstrate highly asymmetric angular dependence with polarity switching at the plasmon resonance conditions. The effects are attributed to coupling between localized and propagating plasmons and discussed in the frame of the electromagnetic momentum loss approach.
