Problems solved by technology

This kind of metamaterial lens has complex structure and high production cost

Metamaterial units made of fewer layers of metal structures can achieve 360° phase shift adjustment by adjusting the parameters of different parts of the metal structure and combining them. However, such metamaterial units have high transmission loss, which is not conducive to the gain of metamaterial lens antennas, etc. performance improvement
