With this support we developed, implemented, and validated a suite of computational tools for the optimal design of phononic materials using topology optimization. Specifically we have Developed an analysis and optimization code to handle large sized 3D elastic wave propagation problems in heterogeneous media by implementing a parallel solver to handle large systems described by complex-valued systems of equations. Verified our ideas and tested the code on a number of numerical examples in 2D and 3D. Studied many problems regarding 2D and 3D bulk and surface waves and their use to create wave guiding devices. Developed and implemented an approach to design phononic bandgap materials on a periodic cell.
