1. An eye-like focusing metasurface system driven by a supervised-evolving learning algorithm, comprising:
a transmissive metasurface,
an array probe,
a focusing guidance module, and
an evolving learning module,
wherein, after an external electromagnetic wave signal penetrates through the transmissive metasurface, the array probe arranged behind the transmissive metasurface detects external electromagnetic wave data, the focusing guidance module and the evolving learning module analyze an external electromagnetic wave and output a regulation and control strategy for the transmissive metasurface, and a state of the transmissive metasurface changes; then the array probe collects new external electromagnetic wave data, and the focusing guidance module and the evolving learning module further analyze an intensity and characteristics of the external electromagnetic wave data and output a next regulation and control instruction; and
the process is repeated until the external electromagnetic wave is focused to a specified position.
