Do Fresnel coefficients exist?
D. Felbacq, B. Guizal, F. Zolla
The starting point of the article is the puzzling fact that one cannot recover the Fresnel coefficients by letting tend the width of a slab to infinity. Without using the so-called…

Ultra-refraction phenomena in Bragg mirrors
Didier Felbacq, Brahim Guizal, Frederic Zolla
We show numerically for the first time that ultra-refractive phenomena do exist in one-dimensional photonic crystals: we exhibit the main features of ultra-refraction, that is the…
