Electromagnetic waves in photonic crystals: laws of dispersion, causality and analytical properties
Boris Gralak, Maxence Cassier, Guillaume Demésy +1
Photonic crystals are periodic structures which prevent light propagation along one or more directions in certain frequency intervals. Their band spectrum is usually analyzed using…
Modal analysis of wave propagation in dispersive media
M. Ismail Abdelrahman, B. Gralak
Surveys on wave propagation in dispersive media have been limited since the pioneering work of Sommerfeld [Ann. Phys. 349, 177 (1914)] by the presence of branches in the integral e…
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…
A route to all frequency homogenization of periodic structures
Yan Liu, Sébastien Guenneau, Boris Gralak
We start from a one-dimensional periodic multilayered stack in order to define a frequency power expansion of effective permittivity, permeability and bianisotropic parameters. It…
Multiple-scattering method applied to gyrotropic media
Wojciech Śmigaj, Boris Gralak
We present an extension of the multiple-scattering calculational method to the case of gyrotropic media.
All-optical octave-broad ultrafast switching of Si woodpile photonic band gap crystals
Tijmen G. Euser, Adriaan J. Molenaar, J. G. Fleming +3
We present ultrafast all-optical switching measurements of Si woodpile photonic band gap crystals. The crystals are spatially homogeneously excited, and probed by measuring reflect…
