Hello,
I am trying to implement a bandgap diagram on a unit cell strurcture using Master/Slave Boundaries on y axis and Perfect H on x axis. On the top, there is a PML Boundary. The result diagram is shown below:

Can anyone tell me why this happen from 0 to 40 degrees?
Are the settings of the PML responsible for this?
Thank you...
