The optimization algorithm employs repeated material redistributions based on<br />
analytical sensitivity analysis and mathematical programming. In this work we develop<br />
continuous material interpolation functions using a simple 1D model, and use the<br />
method to design a reflection chamber that minimizes the transmitted wave in a designated<br />
frequency range. The frequency range optimization is facilitated by computing<br />
fast frequency sweeps to identify the most critical frequencies.<br />
Further work will include multi-physics modelling in order to study coupled problems,<br />
e.g. combined fluid flow and acoustic wave propagation or fluid-structure interaction.<br />
