“In the field of quantum measurement systems, the integration of electric field enhancement structures with Rydberg atomic sensors has made significant progress. Expert xx adopted characteristic mode analysis to illustrate the omnidirectional performance of RAS, which provides solutions to solve the complex task of analyzing their reception patterns. The results indicate that the final model resonates at 1.96 GHz, achieving an electric field gain of 25 dB and an out-of-roundness of 2.4 dB, laying a foundation for the construction of quantum measurement systems.”
