Background,Motivation and Objective These last years,numerous applications have emerged from the research field of Phononic Crystal(PC):frequency filters,wave collimation,super-resolution lenses… These applications are based on unusual dispersion properties of the waves in a periodic structured material(anisotropy,forbidden frequencies band,negative or zero angle refraction,hybridization gap,…).
