Absztrakt:
The measurement of nanoplasmonic near fields is a fundamental question of
nanooptics.  A new method [1] was introduced at the beginning of this year
that utilizes ultrafast photoemission from plasmonic nanostructures and is
capable of probing the maximum nanoplasmonic field enhancement.
In this talk I will give a short introduction to plasmonic structures, present
the details of the new method and give insight into the finite-difference
time-domain simulations that were performed at ELI-ALPS for the validation of
the field enhancement values measured by applying the novel approach.
