Hi all,
My question is about the dispersion diagram for low frequencies, say 200MHz or 300MHz. Although the reflection phase of my unit cell shows a zero phase within these low frequencies but the dispersion diagram dose not coincides with the reflection phase. I mean the first TM mode shows a lower frequency band gap at about 600MHz, i am alittle bit confused.
Please is there any relation to the adjustment of the PML, i.e. the minimum frequency in the PML step (I changed it from the default value to 100MHz as well as the minimum frequency in the setup) and when could we use more than one PML.
