摘　　要：提出了一种适合非对称共面波导的FDTD电磁数值计算激励方式。在此基础之上定义了传输衰减均值A,以表征激励设置的优劣程度。使用EMPro2010进行了大量数值仿真,在所得数据的基础上进行了数值拟合,给出了所提出激励方式下非对称共面波导、共面波导最佳激励位置的近似公式及适用范围。A method on asymmetric coplanar waveguide excitation setting in FDTD computation was proposed, and a transmission mean variable A was defined which describes the good or bad of different excitation settings. Large numerically simulations were made with EMPro2010, and the numerically fitting was done based on simulation data. Finally the formulas of excitation position for both coplanar waveguide and asymmetric coplanar waveguide and their application ranges were presented.
