reflection phase diagram of ebg/pbg surface using CST

Dear vulehuy93,
The results you showed is for PEC and as you can see it is showing 180 degress for all the frequencies as expected. To get the desired results do as follows:
1. make a unit cell with all the original dimensions but take all material as vacuum. In probe results look for argument and note the phase for maximum frequency.
2. now make original unit cell with all material as PEC and then simulate.
3. Lastly, simulate the unit cell with all original materials. Run the macro provided in this simulation and fill the Fmin, Fmax, phase value which you noted for vacuum simulation and PEC simulation file name. Run the macro and if you entered everything correct, you should get the desired result.
PS- Make x-y as periodic and keep Zmax=open add space, Zmin=electrical except for vacuum case where Zmin=open
Hope it helps.
Regards
Praful

Hi,
I cannot see the attachment for the micro. Can somebody help me?
