Floquet wave properties in a periodically layered medium
Martine Rousseau · The Journal of the Acoustical Society of America · 1989
In a periodically stratified medium, the acoustic propagation for wavelength of the order of the period is conveniently described by Floquet waves. A first part of this paper is concerned with a fluid medium and it completes previous results showing the existence of a pseudocritical angle. The extension to an elastic medium allows the introduction of the shear effects inside the layers. Several properties of Floquet waves are exhibited; the particular case of a medium composed of fluid and solid layers is also studied.
