摘要
It is shown that the transmission resonance of acoustic waves for an incident wavelength larger than the period of the grating exists in acoustic gratings with very narrow slits similar to that of optical subwavelength systems. The results are obtained by multiple-scattering numerical simulations. The physical origin for such an acoustic transmission resonance is also analyzed.
