Negative refraction of elastic waves in 2d phononic crystals: contribution of resonant transmissions to the construction of the image of a point source

HIGHLIGHTS

• who: Anne-Christine Hladky-Hennion and colleagues from the InstitutBoulevard Vauban, Lille, France have published the paper: Negative refraction of elastic waves in 2D phononic crystals: Contribution of resonant transmissions to the construction of the image of a point source, in the Journal: (JOURNAL) of 21/Dec/2011
• what: The aim of this paper is to analyze in more details the pressure field in the region where the focalization occurs to understand which parameters are of interest for the image construction.
• how: To determine the allowed directions in the pressure field a double . . .
