Theoretical Model for Solving the Inverse-Problem of Dynamic Equivalent Media of Periodic Rod-Beam ibration forms are obtained according to the vibration theory. Finally, the dynamic equivalent material parameters of the structure under different vibration forms are calculated by combining the relations between frequency, wave vector, vibration form, and vibration energy with the expressions of d

,Ältere Arbeitnehmer in der Gesellschaft,ppears in the transmission path of vibrations, it is always one of the main objects in the field of vibration and noise control. In this chapter, using the basic theories of acoustic metamaterials and combined with the first kind of inverse problem in vibration problems, we propose a method for calc
