In this presentation, we will introduce our recent work on the reconstruction of plasmonic near-fields under precisely tailored polarization states of the driving light. The main outcome of this study is a novel imaging technique – essentially based on energy-filtered PINEM and Lorentz TEM – enabling the extraction of complementary information (e.g., the phase) of plasmonic excitations at the nanoscale.
