Hello!
I am looking for software tool to model EAS (electronic article surveillance) system – so called swept RF systems with central frequency 8.2 MHz.
To re-phrase it in physical terms:
For closely spaced electrically small (x < λ/10) loops of different shapes I want to
- output spatial field distribution and determine field strength at different points in space
- determine coupling coefficient between the loops (S21)
- quantify effect of small resonant circuits placed in the vicinity of the loops on coupling coefficient (changes in S21 when resonant circuit is present).
Ideally software should have functionality to add discrete L-C-R components to the loops terminals – to study effects of matching networks.
If anyone has experience with this type of problems please recommend good software tool.
Ideally looking for open source but commercial software is of some interest too.
