Abstract
The spatiotemporal evolution of a SPP wave packet with femtosecond duration is experimentally investigated in two different plasmonic focusing structures. A two-dimensional reconstruction of the plasmonic field in space and time is possible by the numerical analysis of interferometric time-resolved photoemission electron microscopy data. We show that the timeintegrated and time-resolved view onto the wave packet dynamics allow one to characterize and compare the capabilities of twodimensional components for use in plasmonic devices operating with ultrafast pulses.
