摘要：
In this contribution, we focus on the analysis of complete omnidirectional acoustic band gaps in additively manufactured three-dimensional (3D) phononic crystals. We present a numerical analysis of band structure and phononic band gaps of different cubic unit cell geometries. For validation, we report experimental results for transmission of acoustic waves in different characteristic spatial directions through various phononic crystal samples. These results are supplemented by numerical transmission analysis. The elements form the building blocks of wideband, high-resolution phononic-fluidic systems for measuring physical properties such as fluid density, speed of sound, and concentration.
