Re: Reflection Phase Diagram of PEC and PMC in CST
Hi

I downloaded macro for calculate reflection phase, but i donītknow how I used it, I copied it to macro CST MWS directory but I donīt know how run it...Can me everyone give instruction...?thanks very much

Hi abdoeng

i was looking at your uplaoded model for WGA method.
i dont understand the following points:

1: why you are using waveguide port as well as farfield source?

2: how you get this graph of phase vs length?

3: and also what is this length? as i cant see any variable defined in your model file?

i hope you will understand what i am asking.

thanks

hi prafuldeo


you mentioned vaccum model , what do you mean by that ?
did you use macro or WGA method to simulate PMC reflection diagram.

thanks

Hello Shahid,
Since WGA method is much quicker and its easy to do parameter sweep with WGA method, I use this only. But I always cross check the final results with macro method for accuracy and till now I am getting same results with both so any method will do.

Reflection Phase Diagram of PEC and PMC in CST
Hi everyone,

I have a problem. I am simulating a FSS cell in CST Studio and I want to calculate the reflection coefficient in a frequency range with a plane wave (TEM mode). I am using a waveguide, but I am not sure which mode I am exciting with a waveguide. Any of you can you tell me how to excite a TEM mode with a waveguide port.

Thanks in advance,

David

you have to check the ports E and H fields on both ports. and check the validation of TEM mode
