This paper presents an overview of the recents studies on the ultrasonic transmission through subwavelength holes arrays. The role of the geometrical parameters of the perforated plates in the transmission features has been reported by using a theoretical model under the rigid-solid assumption. It is shown that the transmission spectrum can be tailored by varying the geometrical parameters.
