| 摘 要： | 通过对谐振腔微扰法的理论分析,利用电磁仿真软件求解材料微波频段的复介电常数。在软件中分析谐振腔与样品的网格单元尺寸对结果的影响,求出最优解的网格单元尺寸作为其标准用来实现微波频段的多频点测量,并进行叠层型两相复合材料的仿真预测。结果表明:在多频点测量准确度较高,并对预测复合材料的复介电常数具有一定的指导性。

Simulation Study on Material Measurement of Complex Permittivity by Cavity Perturbation Method |
| |
| Abstract: | Solution of complex permittivity of material in microwave frequency band can be deduced by a theoretical analysis of cavity perturbation method and using electromagnetic simulation software.Multi-fre-quency point measurement of microwave frequency band is accomplished and simulation and forecast of laminated two-phase composite are conducted by taking sizes of grid cell of optimal solution as its stand-ards,which is deduced from analysis of influence of sizes of grid cell of resonant cavity and samples on re-sults in software.The results indicate that measurement on multi-frequency point has higher accuracy which have a certain guidance on forecast of complex permittivity of composites. |
