Box 10, Bellingham, WA 98227-0010, United States Abstract: This paper presents modeling and analysis methods for design of a acoustic metamaterial panel consisting of two isotropic plates and small membrane-mass subsystems for absorption of low frequencies transverse elastic waves. Two models of a unit cell are derived and used to demonstrate the existence of negative effective material properties. Moreover, the design of experiment sample confirms that the model and analysis methods are valid. (1) The frequency of the membrane-mass subsystems are uniform distribution in whole acoustic metamaterial panel have two vibration models. (2) The different distributions of membrane-mass subsystems and their resonance frequencies result in different vibration isolation characteristics. (3) PSV is used to test and the result show that a low frequency wave absorber does not require nano-manufacturing techniques. (4) If we design the frequency of the membrane-mass subsystems different it can change the character of the metamaterial panel. © 2013 SPIE.
