The goal of this project is to fully characterise nanoplasmonic systems and their interaction with light. We want to understand the spatio-temporal structure of the enhanced electric fields at nanostructured samples (e.g. antenna systems). One powerful method to characterise electric field directly is attosecond streaking. We have shown theoretically that the electric fields of plasmons can be recovered from attosecond streaking traces.
We have demonstrated experimentally that streaking is possible from non-crystalline samples.
