所以该方法可以帮我们实现偏振态的固定。 2,该仿真波导的外边界为散射边界条件Scattering Boundary Condition,可以一定程度上使得被光栅结构散射的光透射出去,达到仿真无穷大空间的效果,该设置虽然比完美匹配层Perfectly Matched Layer设置方便,但是效果并没有那么好。 3,和全模型相比,采用半模型可以使网格减半,仿真效率至...

The out-of-plane wave enters from the left boundary and transmits the right boundary without reflection. This can be simulated in theBeam Envelopesinterface by adding aMatchedboundary condition with excitation on the left and without excitation on the right, while adding aPerfect Magnetic Conductor...

In the frequency domain, aperfectly matched layer(PML) is a good alternative for a boundary condition toward “infinity”. The PML formulation, which is available for many different physics interfaces, essentially attenuates outgoing waves so that the reflected energy is very small. The effect is ...
