基于模糊数学的贴片式左手超材料微结构选择方法研究
Fuzzy mathematics based strategy for selecting of the patched left-handed metamaterial microstructures
摘要
Abstract
In this paper,the mechanism for selection of the microstructures of the patch left-handed metamaterials based on fuzzy math is proposed.A set with different topological configurations is obtained from the existing left-handed metamaterials structures.The characteristics of each structure in the set is mapped to [0,1] interval through a certain subordinate function.The degree of the membership represents each structure's conformity to the designing demand.According to the membership degree of the fuzzy objectives and constraints,the fuzzy superiority set is obtained,which can be used to represent the suitable structures for the demand.The determination of the subordinate function of each fuzzy objective and constraint is discussed.In order to validate the feasibility of the method,one set containing the structures with different topology configurations and another consisting of the fork-shaped structures with different size are established.For different objectives and constraints,the superiority of the corresponding set is calculated.The result indicates that the proposed structure selection method can find the required structure configurations.关键词
