- LIS Large Intelligent Surface
- SRA Smart Reflect Array
- RRA Reconfigurable Reflect Array
- the smart surface device is composed of a large-scale device array and an array control module.
- the large-scale device array is a large number of device units that are regularly and repeatedly arranged on a flat bottom plate. In order to achieve considerable signal manipulation effects, hundreds or thousands of device units are usually required to form a device array.

For an incident wave at an angle, the metasurface unit causes a fixed change in the amplitude, phase, polarization and other characteristics of the incident wave. , the corresponding reflected waves are obtained.
- Dynamic reflective array/smart surface device The structure and function of the reflective array can be controlled. For an incident wave at an angle, the amplitude, phase, polarization and other characteristics of the incident wave can be changed through programmable control. , the corresponding reflected waves are obtained.
