Abstract
Space-time-coding metasurface provides a better method for dynamic control of electromagnetic waves. We think it can improve the test systems that used to require multiple probes in different directions. In this paper, we propose an emulator based on programmable metasurface to solve the measurement problems in wireless communication system. it can dynamically emulate the field of receiving equipment at a specific location in complex communication environment. The hologram and corresponding quantization technique are used to complete the calculation of the metasurface. We also describe the implementation and analyze the feasibility of our emulator.
