This invention proposes a design method for impedance-gradient metamaterials, which includes: calculating the impedance-gradient metamaterial set X = {x 1 ,…,x k The corresponding evaluation function result set Y(X) = {y} 1 ,…,y k The process involves calculating the mean and variance of the evaluation function result set Y(X), and then calculating the prior distribution function based on the mean, variance, and evaluation function result set Y(X). A data acquisition function is then calculated based on the minimum value in the evaluation function result set Y(X), the prior distribution function, and the variance. An iterative operation is performed to obtain the optimal impedance-gradient metamaterial corresponding to the maximum value in the data acquisition function. At the end of the iterative operation, the thickness and / or impedance of each metamaterial layer in the multiple metamaterial layers characterized by the optimal impedance-gradient metamaterial, as well as the arrangement of the multiple metamaterial layers, are output. This effectively shortens the design time of the impedance-gradient metamaterial and improves the design effect.
