A class of invisible inhomogeneous media and the control of electromagnetic waves
Benjamin Vial, Yangjie Liu, Simon A. R. Horsley +2
We propose a general method to arbitrarily manipulate an electromagnetic wave propagating in a two-dimensional medium, without introducing any scattering. This leads to a whole cla…
A coupling model for quasi-normal modes of photonic resonators
Benjamin Vial, Yang Hao
We develop a model for the coupling of quasi-normal modes in open photonic systems consisting of two resonators. By expressing the modes of the coupled system as a linear combinati…
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…
Transmission enhancement through square coaxial apertures arrays in metallic film: when leaky modes filter infrared light
Benjamin Vial, Frédéric Bedu, Hervé Dallaporta +6
We consider arrays of square coaxial apertures in a gold layer and study their diffractive behavior in the far infrared region. These structures exhibit a resonant transmission enh…
Resonant metamaterial absorbers for infrared spectral filtering: quasimodal analysis, design, fabrication and characterization
Benjamin Vial, Guillaume Demésy, Frédéric Zolla +7
We present a modal analysis of metal-insulator-metal (MIM) based metamaterials in the far infrared region. These structures can be used as resonant reflection bandcut spectral filt…
Quasimodal expansion of electromagnetic fields in open two-dimensionnal structures
Benjamin Vial, Frédéric Zolla, André Nicolet +1
A quasimodal expansion method (QMEM) is developed to model and understand the scattering properties of arbitrary shaped two-dimensional (2-D) open structures. In contrast with the…
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…
