Embodiment
[0032] Here we give the specific process of designing the x-band circularly polarized folded transmission array, and in the actual design process, it can be extended to a specific operating frequency range according to the application requirements.
[0033] 1 Top metasurface design
[0034] The top metasurface unit structure is as figure 2As shown in (a), it includes a metal radiation layer, a dielectric substrate, a metal backplane, a dielectric substrate, and a metal receiving layer from top to bottom. A hole is opened in the middle of the metal backplane so that the metal radiation layer and the metal receiving layer pass through the metal The hole form realizes electromagnetic energy coupling. Among them, the metal materials of the three layers of metal radiation layer, metal backplane and metal receiving layer are good conductors, such as copper, silver, gold, etc.; the materials of the two layers of dielectric substrates are low-loss dielectric materials, such as resin...
