It first describes the experimental set-up at the laboratory scale. This laboratory scale configuration allows people to carefully study the roles of the flexural and compressional resonances inside the forest of rods for the out-of-plane wavefield measured on the plate surface. The chapter then discusses the field pattern issued from point-like sources located either inside or outside the metamaterial in the framework of a simplified theoretical approach, where only one type of Lamb waves in the plate and one type of resonance of the rods (i.e. compressional resonance) are considered. It also discusses the complete wavefield pattern, and magnifies the role of flexural resonances of the rods through different examples.
