摘要： 低频微波在共面波导传输线上是以准TEM（Transverse ElectroMagnetic）模的形式传播，其横向分布的电场和磁场相互作用能够激励出沿导带方向的电磁体积力.通过有限元-棱边元法数值分析了不同频率的激励源对共面波导周围场强分布的影响，并研究了处于特定环境下的共面波导周围的电场、磁场以及电磁体积力的分布情况.结果表明，在相同介质中频率较低的微波具有更大插入损耗，并且能保持良好准TEM模的特征，且导带周围分布的横向电场和磁场相互耦合可以激励出沿导带方向的电磁体积力. 

Abstract: Low frequency microwaves propagate through coplanar waveguide in the quasistatic TEM mode, and the cross section electric field and magnetic field interact to produce electromagnetic body force along the coplanar waveguide. It investigated the influence of frequency on the density fields around the coplanar waveguide. The distribution of the electric field, magnetic field and electromagnetic body force in certain conditions was also discussed. The results show that in the same boundary conditions microwaves of lower frequency can lead to larger insertion loss and keep the quality of being better quasistatic TEM mode. The electromagnetic body force along the direction of coplanar waveguide can be produced through the mutual coupling of the electric field and magnetic field.
