Dielectric media to be set in TEM horn antenna

ዘካርያስ

Hi all,

 

How can i set a dielectric medium in TEM horn antenna i.e. in the free space between upper and lower conductors (as we know a dielectric can only be applied in closed regions) ?

Hi,

 

You should be able to achieve this by setting the required geometry faces to have their 'Face medium' as 'Dielectric boundary'...

 

For example:

1. Create a Cuboid
2. With the cuboid selected, expand the 'Details tree'
3. Set the cuboid region to be your dielectric
4. Set the required PEC faces to be 'Perfect electric conductor'
5. Set the required dielectric-to-air interface faces to be 'Dielectric boundary'

The same process can be applied to your horn antenna geometry by first creating it as a solid (filled) geometry, setting the internal medium and then setting the required face properties.

 

Kind regards,
