摘要：
This paper discusses a level set-based topology optimization method for the design of a ferromagnetic waveguide. The optimization problem is formulated to maximize the power of transmitted waves at prescribed frequencies. A level set-based topology optimization method incorporating a fictitious interface energy is used to find optimized configurations of ferrite materials inside the waveguide. The results of the numerical examples for two different target frequencies show that the presented method successfully finds optimized configurations that maximize transmission power of waveguides for both forward and backward propagation.
