only a single plane wave source is allowed when calculating transmission/reflection coefficients
As shown in the picture, I want to reflect radio waves to a self-made mesh reflector instead of radiating radio waves to a solid reflector using a conical horn antenna, but this error continues to occur."only a single plane wave source is allowed when calculating transmission/reflection coefficients". I want to use a waveguide port without using a plane wave source

Hi @Sunwoo Baek ,
A possible approach:
Calculate the nearfield at the horn antenna's aperture (in freespace) and export efe/hfe files.
Use efe/hfe files to replace the horn by its equivalent nearfield source
Add your mesh reflector
Create two near field requests:
- above the mesh reflector with setting "Calculate only scattered part of the field"
- below the mesh reflector
Exclude or delete the mesh reflector and only keep the upper nearfield request without "Calculate only scattered part of the field". This will be used to normalize the power in POSTFEKO.
In POSTFEKO nf_reflected basically represents the reflection coefficient, nf_transmitted reperesents the transmission coefficent.
Of course you still need to normalize the power in the nearfields by the power in freespace (coming from nf_source_alone.cfx)
Files are attached.
Hope this helps!
Best regards,
Torben
