Abstract
We study theoretically sub-wavelength physical phenomena such as resonant transmission and broadband sound shielding for Lamb waves propagating in an acoustic metamaterial made of a thin plate drilled with one or two row(s) of rectangular holes. One of the main results is the demonstration of a broadband low frequency acoustic shielding with high attenuation.
