[0027] Metamaterials are artificial composite structural materials with supernormal physical properties that natural materials do not possess. The orderly arrangement of microstructures can change the relative permittivity and magnetic permeability of each point in space. Metamaterials can achieve refractive index, impedance, and wave transmission performance that ordinary materials cannot have within a certain range, thereby effectively controlling the propagation characteristics of electromagnetic waves. The metamaterial radome based on artificial microstructures can change the relative permittivity, refractive index and impedance of the material by adjusting the shape and size of the artificial microstructures, so as to achieve impedance matching with air to maximize incident electromagnetic waves. transmission. The frequency can be selected by adjusting the size of the microstructure, and the corresponding transmission and filtering frequencies can be adjusted according to ...
