Embodiment Construction
[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0033] The geometric shape information of a single microstructure unit of a metamaterial is described by a set of parameters, and complex topological structures correspond to many geometric parameters, and the parameters are often mutually constrained. by figure 1 The shown metamaterial structural unit with "snowflake" topology is an example. Such as figure 1 As shown, there are four corresponding geometric parameters {a 1 , a 2 , b 1 , b 2}. define {s 1 =a1 +b 1 ,s 2 =a 2 +b 2}, G is a geometric parameter vector, that is, G=[s 1 ,s 2 ].
[0034] For this structure, assuming that the line width is ignored, the parameter s 1 ,s 2 The value ranges are [1.60, 3.00], [1.60, 3.00] respectively. The experiments are arranged according to the principle of orthogonal experiment design, and each factor takes 0.1 as the step size, then the selec...
