 ===== TERS field enhancement =====
+There are many different results in the literature related to TERS probes. Most typically, the probe is simulated for a single wavelength, using a truncated probe apex and plane wave illumination. This is an easy way how to demonstrate the local field enhancement. However, there are few potential problems:
+Even for truncated probe, some antenna effect can be expected (ideally infinitely extending probe is hard to be simulated). Truncated probe is still far from reality as in real experiments, the probe is large, much larger than what can be simulated unless we make the model consisting of really large voxels, losing some spatial resolution (there is a tradeoff between the detailness of model and its size).
+Staircasing effect can create some extra errors, namely for coarse models.
