【 摘 要 】

We proposed a high-efficiency meta-surface with a parabolic phase distribution that can focus a plane wave to a point image in transmission geometry. For realizing the predicted effects, we use the meta-atoms with 100% transmission to make it. Then we operate the simulation in the CST Microwave Studio to perform the focusing characteristic. The results show that the maximum efficiency is up to 90.6% at 10GHz and the half-power bandwidth is 31.8%, which is better than other previous works.
