Abstract

The invention relates to the technical field of materials, in particular to a wave-absorbing material parameter determination method and device, computer equipment and a storage medium. The wave-absorbing material parameter determination method is applied to a to-be-optimized wave-absorbing material, and comprises the following steps: solving a sub-objective function of each material parameter category in the to-be-optimized wave-absorbing material to obtain a single-objective optimal solution of each sub-objective function; for each material parameter category, determining a corresponding linear membership function according to the single-target optimal solution; constructing a comprehensive fuzzy objective function of the to-be-optimized wave-absorbing material according to the intersection of all the linear membership functions; the comprehensive fuzzy objective function is optimized and solved on the basis of a hybrid optimization algorithm by taking material parameter categories in the to-be-optimized wave-absorbing material as solving objectives, and a comprehensive optimal solution is obtained; and determining each optimization value in the comprehensive optimal solution as an optimization target value of the corresponding material parameter category. The invention provides a multi-layer wave-absorbing material which can balance various material parameter types such as thickness, wave-absorbing characteristics and frequency band width.
