Embodiment Construction
[0028] Metamaterials are artificial composite structural materials with extraordinary physical properties that natural materials do not have. Through the orderly arrangement of microstructures, the relative permittivity and magnetic permeability of each point in space can be changed. Metamaterials can realize within a certain range the refractive index, impedance, and wave-transmitting properties that ordinary materials cannot possess, so that they can effectively control the propagation characteristics of electromagnetic waves. The broadband wave-transparent metamaterial based on artificial microstructure can change the relative permittivity, refractive index and impedance of the material by adjusting the shape and size of the artificial microstructure, so as to achieve impedance matching with air and maximize the incident electromagnetic wave. transmission. And the frequency can be selected by adjusting the size of the microstructure, and the corresponding wave-transmitting ...
