Propagation of THz beam

Sometimes, one want to measure a THz beam profile in a plane that is not accessible experimentally, or where the beam waist is so small that only a few pixels would be excited. To overcome this problem, one makes the measurement elsewhere, and then computes the beam profile at the desired location, using a Fourier propagator.

A matlab program that takes as input the amplitude and phase images from the camera, permits to make the back-propagation.

Work in nano-optics

We use a theoretical approach based on the regularization of Singular Scattering operators, and the expansion of a compact non-linear eigenvalue problem. The final goal is to obtain a precise modal expansion for the field scattered by nanoparticle(s), possibly on substrate, see [http://dx.doi.org/10.1364/OE.24.027137] .

This work takes a place between Mathematics and Physics, and paves the route for new modeling tools in Applied Physics. Indeed, it permits to obtain accurate but scalar models of complex systems, where the (heavy) computation of 6 field components in 3D space, for each frequency and excitation condition (angle, polarization) is replaced by a the computation of a few complex numbers that characterize the system: the QNM Eigen frequencies and some volume integrals of their modes.

The reduction of complexity is drastic, while preserving quantitative modeling.

Eventually, it is the field map of the mode that contains all the information on the spatial variation of fields, whereas the expansion coefficients (often a few of them are needed), contains the information on frequency (or time) variation.
