Prior-Knowledge-Guided Structural Optimization Method for Microwave Component Design

A novel prior-knowledge-guided structural optimization (PK-SO) method is proposed for microwave component design. The proposed method takes advantage of prior knowledge to construct variable structure units and combine grey wolf optimizer to improve the structure of microwave components. In this work, the performance of the PK-SO method is explored using a waveguide transformer as an example. The results show that the PK-SO method is suitable for microwave component design.
