Abstract
The present research consists to optimize and predict experimental
results for near field optic and microscopy.
At the first stage, it convient to predict the influence of three
experimental parameters:
- 1) The optimal detection conditions, where a detected signal will be
maximum.
- 2) Plasmon resonance conditions, taking into account the object but
also the distance between the near-field probe and the object
(possible modifications of resonance conditions, in order to obtain
a measurable signal).
- 3) Light conditions (reflexion, angle, polarization).
In order to increase the ratio signal/noise in Raman microscopy and thus
to optimize these parameters, we must simulate numeritically the
selected system and modifie the influent parameters.
The development of a such method for the 3D resolution is the main aim
of this research. It is based on a Finite Elements method and will
be verified and confirmed with a coupled-dipole method.
