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
- 1) The optimal detection conditions, where a detected signal will be
- 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.
