Part 1
Luc Jaouen

Wave propagation in :
1. air & "equivalent fluid" (i.e. materials with rigid motionless skeletons)
2. solids (i.e skeletons in vacuum)
3. porous materials with elastic skeletons (i.e. Biot's theory)

These slides are the result of a long-time collaboration with my colleagues at Matelys :
Fabien Chevillotte and François-Xavier Bécot.

To move through the slides, use the ← and → buttons (top corners of the screen) or the same cursor keys if you have a keyboard.

About the plot :
The cartoon image of SpongeBob SquarePants is a tribute to the work by late Stephen Hillenburg. This drawing has been done from scratch for the purpose of this page : there's no way you will find Bob cut in two halves like this in the original TV show and comics. I thus assume this is not an infringement of Viacom's copyright.
