【摘要】：研究了基于模糊數(shù)學(xué)的貼片式左手超材料結(jié)構(gòu)的選擇機(jī)制,其核心思想是基于現(xiàn)有左手超材料結(jié)構(gòu)構(gòu)建左手材料微結(jié)構(gòu)集合,將集合中結(jié)構(gòu)的特性參數(shù)以某種隸屬函數(shù)映射到[0,1]區(qū)間,用隸屬度表示各元素對(duì)設(shè)計(jì)需求的符合度;根據(jù)模糊目標(biāo)及約束的隸屬度確定元素的模糊優(yōu)越集,最終找到最適合于相應(yīng)設(shè)計(jì)的結(jié)構(gòu)方案。給出了材料庫中每種結(jié)構(gòu)方案相對(duì)于模糊目標(biāo)及約束的隸屬度的確定方法。為了驗(yàn)證所提出選擇方法的可行性,建立了不同拓?fù)湫问降淖笫殖牧蠘?gòu)型集合和不同尺寸的巾型構(gòu)型集合,針對(duì)具體的設(shè)計(jì)目標(biāo)和約束要求,計(jì)算了相應(yīng)集合的模糊優(yōu)越集,給出了最適合的個(gè)體元素排序,計(jì)算結(jié)果表明本文提出的結(jié)構(gòu)選擇方法可選出滿足設(shè)計(jì)要求的結(jié)構(gòu)構(gòu)型。
[Abstract]:The selection mechanism of the laminated left-handed metamaterial structure based on fuzzy mathematics is studied. Its core idea is to construct a set of left-handed material microstructures based on the existing left-handed metamaterials. The characteristic parameters of the structure in the set are mapped to the interval of [0 ~ 1] by a certain membership function, the degree of conformity of each element to the design requirement is expressed by the membership degree, and the fuzzy superior set of the element is determined according to the membership degree of the fuzzy object and the constraint. Finally find the most suitable for the corresponding design of the structure. A method for determining the membership degree of each structure scheme relative to fuzzy targets and constraints in the material library is presented. In order to verify the feasibility of the proposed selection method, a set of left-handed metamaterials with different topologies and a set of towel configurations with different sizes are established, and the fuzzy superior sets of the corresponding sets are calculated according to the specific design objectives and constraints. The most suitable sorting of individual elements is given. The results show that the structure selection method proposed in this paper can select the structural configuration that meets the design requirements.
