This dissertation presents new techniques for sound field engineering of open acoustic systems. Numerical tools are developed to simulate open acoustic systems in the frequency domain. Acoustic metamaterials are analyzed and designed using normal modes. In addition, the interaction between meta-atoms is studied and the coupling is investigated as a parameter for tuning the acoustic performance of metamaterials. Fano resonances induced by bound states in the continuum are also studied. The results of this research will enable, among other things, the engineering of high-quality Fano resonances in open acoustic systems.
