磁耦合定向耦合器仿真设计

The Simulation Design of Magnetic Coupling Directional Coupler

在分析波导中场模式基础上,通过仿真计算和优化,得出影响定向耦合器磁耦合的主要因素,并在此基础上提出利用磁环耦合设计双耦合度定向耦合器和可变耦合度的定向耦合器的设想。通过仿真,所得结果和理论分析相吻合,证明了设计方案的可行性。

This paper obtained main factors for magnetic coupling directional coupler by simulation and optimization based on the field mode analysis of waveguide. Under these analysis, double coupling factor and variable coupling factor directional coupler design based on magnetic coupling is conceived. The simu- lation results coincide with the theoretical analysis which proved the feasibility of this design scheme.
