Shape Optimization of an Acoustic Demultiplexer with 4 Ports

Application ID: 73611

A demultiplexer is a device that directs different frequency bands to different outputs. In this tutorial model, we will design a demultiplexer by performing shape optimization on all initial circular boundaries in a sonic crystal (phononic crystal) configuration. The model uses shape optimization with Helmholtz regularization together with a MinMax formulation for the power ratio of the three output ports.

This model example illustrates applications of this type that would nominally be built using the following products:
