Polarization Channel HH,HV,VH,VV

Altair Forum User

Hi all

 

I was trying to simulate a trihedral corner reflector and read all four polarization channel HH,HV,VH,VV but I could not do it. How can that be done 

 

What I did is I had a plan wave and two far field one horizontal and the other is vertical..... is that right ?? and how can I read all the four polarization channel from the trihedral corner reflector??

 

Thanks

Hello Abdullah,

 

It looks like you almost have the full solution. Currently you have a single plane wave with a single polarisation and you add two far field requests. Let me assume your plane wave is currently vertically polarised, you thus currently calculate VV and VH. What you are missing is a second configuration where the plane wave source is horizontally polarised (with the same far field requests) so that you can calculate HV and HH. I'm assuming that you use CADFEKO to create your model (not EDITFEKO) and thus you should be able to modify your model by performing the following steps:

• Duplicate the configuration that you already have
• Set the sources to be 'per configuration' (it is an option on an icon that is a gear with four colour blocks on it - next to the + icon on the configuration tab)
• Select the second configuration, open the source dialog and set the polarisation to 90 (assuming it is currently the default 0)

The second configuration's far fields will give you the HV and HH polarisations.
