Metamaterial regulation and control element testing system

The utility model belongs to the technical field of metamaterial testing, and relates to a metamaterial regulation and control element testing system which comprises a testing clamp, an external field source, a regulation and control element to be tested and a vector network analyzer, the vector network analyzer is electrically connected with the testing clamp, the regulation and control element to be tested is arranged inside the testing clamp, the external field source is arranged outside the testing clamp, and the external field source is electrically connected with the testing clamp. The external field source inputs an external signal into the to-be-tested regulation and control element, the vector network analyzer measures resonance parameters of the test system under the influence of the external signal on the to-be-tested regulation and control element, the to-be-tested regulation and control element is a regulation and control element sensitive to voltage or light irradiation intensity, and the extern
