Embodiment Construction

[0049] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0050] Taking the design of two double-beam dual-polarization artificial electromagnetic surfaces and one three-beam multi-polarization artificial electromagnetic surface as examples, the method for designing a multi-beam multi-polarization artificial electromagnetic surface based on deep learning of the present invention is described.

[0051] First, we choose a random discrete lattice as the basic pattern of unit particles, such as figure 1 . The lattice pattern includes 16×16 small squares, wherein the gray small squares are metal blocks, and the white small squares are air blocks, that is, they are not covered with any material. The gray small square is marked as "1", and the white small square is marked as "0", which correspond to "1" and "0" in the deep learning design algorithm, and are marked as 1bit unit code. The different two-dime...

Description

technical field [0001] The invention relates to a method for designing an artificial electromagnetic surface, in particular to a method for designing a multi-beam multi-polarization artificial electromagnetic surface based on deep learning, which belongs to the field of deep learning and programmable artificial electromagnetic surfaces. Background technique [0002] New artificial electromagnetic materials (Metamaterials) refer to artificial composite materials with special conduction or radiation characteristics (negative refraction, zero refraction) when electromagnetic waves propagate in them. Magnetic materials with magnetic permeability requirements. Different from the original three-dimensional sub-wavelength artificial electromagnetic materials, the artificial electromagnetic metasurface (Metasurface) is an ultra-thin two-dimensional array surface, which is designed by regularly arranging sub-wavelength artificial electromagnetic materials into a planar array. Furthe...
