Enhanced tunability in ferroelectric composites through local field enhancement and the effect of disorder
Benjamin Vial, Yang Hao
We investigate numerically the homogenized permittivities of composites made of low index dielectric inclusions in a ferroelectric matrix under a static electric field. A refined m…

Adaptive perfectly matched layer for Wood's anomalies in diffraction gratings
Benjamin Vial, Frédric Zolla, André Nicolet +2
We propose an Adaptive Perfectly Matched Layer (APML) to be used in diffraction grating modeling. With a properly tailored co-ordinate stretching depending both on the incident fie…

Finite Element Method (Chapter from "Gratings: Theory and Numeric Applications")
Guillaume Demésy, Frédéric Zolla, André Nicolet +1
In this chapter, we demonstrate a general formulation of the Finite Element Method allowing to calculate the diffraction efficiencies from the electromagnetic field diffracted by a…
