On the Use of Normalized Gaussian Network for Topology Optimization of Planar Components

In this paper, a novel topology optimization scheme based on normalized Gaussian network (NGnet) is proposed for design of planar microwave components. Since NGnet can treat the fine mesh structure with a lower dimension of design matrix, NGnet can be expected to improve the optimization efficiency of component design. Performances of the proposed NGnet-based optimization scheme is demonstrated by challenging the dynamic range of generalized inductance and generalized capacitance of a small planar structure on PCB. Results show that the widest dynamic range are acquired by NGnet-based scheme with interval of 4 and radius of 3, and the average optimization time is reduced by almost 70% than the traditional optimization scheme.
