Abstract
We study the resonant acoustic transmission through compound subwavelength periodichole arrays. Fabry–Perot resonance peak splitting is found. We can attribute thephenomenon to phase resonances via calculating the phase difference between adjacentholes in a unit cell. Furthermore, by analyzing the transmission characteristics of differentkinds of compound hole arrays for normal and non-normal incidence, it can bedemonstrated that the phase resonances arise from the coupling between holes in a unitcell. In addition, we also discuss the transmission resonance originating from acousticsurface modes and illustrate the hybridized features of acoustic surface modes andFabry–Perot modes. The results are expected to have advantages in tailoring resonantacoustic transmission properties.
