摘　　要：为了对电磁波在介质板附近的能量守恒实验进行理论上的指导,对电磁波反射与折射实验中的能量守恒进行了分析。对无限大介质板的反射与折射和介质板处的能量守恒进行了理论计算,对实测结果进行了分析,并利用电磁仿真软件对实验进行了仿真。将仿真结果与理论结果和实验测试结果进行了对比分析,结果表明实验测试结果与实验的仿真结果更为接近,与无限大介质板的理论结果有较大的差距。The energy conservation in electromagnetic wave reflection and refraction experiments is analyzed in order to provide theoretical guidance for the energy conservation experiment of electromagnetic waves near a dielectric plate.Theoretical calculations are made for the reflection and refraction of the infinite dielectric plate and the conservation of energy at the dielectric plate.The measurement results in the experiment are analyzed.The experiment is simulated using electromagnetic simulation software.The simulation results are compared and analyzed with the theoretical results of energy conservation and the measured results.It's shown that the experimental results are closer to the simulation results of the experiment than theoretical results of an infinite dielectric plate.
