Abstract

The invention discloses an intelligent design method of a digital coding metamaterial unit. The method comprises the steps of 1) carrying out digital coding on a basic pattern of a 1-bit unit for constructing a metamaterial, and predicting unit polarization wave reflection phases during arrangement of different modules in the 1-bit unit by adopting a deep learning design algorithm; and 2) determining a polarization wave phase difference theta of a 1-bit unit structure for constructing the metamaterial according to a function requirement of the metamaterial, and designing the 1-bit unit structure with the polarization wave phase difference theta in combination with a binary particle swarm optimization algorithm module and a deep learning module. The design method provided by the invention realizes automatic design of an ideal reflection phase of a multi-bit unit on the basis of deep learning, has high efficiency and simplicity, is good in expansibility, can replace software to perform simulation, and lowers and shortens the corresponding complexity and time of obtaining information of a coding unit; and a multi-beam multi-polarization artificial electromagnetic surface is quickly and simply designed.

Description

technical field [0001] The invention relates to a design method of a metamaterial unit, in particular to an intelligent design method of a digital coded metamaterial unit, which belongs to the field of machine learning and digital coded metamaterials. Background technique [0002] Artificial composite materials with special conduction or radiation characteristics (negative refraction, zero refraction) when electromagnetic waves propagate in them are called new artificial electromagnetic materials (Metamaterials). Electromagnetic materials with dielectric constant and permeability requirements. In order to achieve different functions of metamaterials, the phase change can be achieved by adjusting the metamaterial unit structure, and then adjusting the distribution of units with different reflection phases can make the incident wave radiate a highly directional pencil beam or liner beam through the array structure. [0003] The phase response of the coded unit (16×16 random l...
