We study the resonant acoustic transmission through compound subwavelength periodic hole arrays. Fabry-Perot resonance peak splitting is found. We can attribute the phenomenon to phase resonances via calculating the phase difference between adjacent holes in a unit cell. Furthermore, by analyzing the transmission characteristics of different kinds of compound hole arrays for normal and non-normal incidence, it can be demonstrated that the phase resonances arise from the coupling between holes… CONTINUE READING
