| 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. |
