specific Embodiment approach 1
[0033] Specific implementation mode 1. Combination Figure 1 to Figure 5 Describe the present embodiment, the method for obtaining the electromagnetic scattering characteristics of the cylindrical frequency selective surface described in the present embodiment, the method analyzes the electromagnetic scattering characteristics of the cylindrical frequency selective surface structure, the cylindrical frequency selective surface structure, which includes metal plate 1 and a dielectric layer 3 with a thickness of dmm, the dielectric constant of the dielectric layer 3 is ε r, the magnetic permeability is 1; the surface of the metal plate 1 is engraved with through holes 2 in the shape of a rectangular grid, and the shape of the through holes 2 is Y-shaped, and every two adjacent Y-shaped holes are along the column surface. The spacing is 40mm, the metal plate 1 is bent according to the radius of curvature of the cylinder as P, and the dielectric layer 3 is attached to the inner si...
