Has anyone used Sonnet software for EM Simulations? I recently saw an add of a freeware version of Sonnet Suite called Sonnet Lite. Downloadable from **broken link removed**
I managed to see the help and run a simulation... But still have no clue on what I did. It appears as if I had to choose a PCB, the dielectric layer above and below it, Place metal on it ground every piece of metal, ad some ports and run a simulation and view a gain v/s frequency curve....
Have you read the documentation? It is very descriptive, anyway Sonnet is what is referred to as a 2.5D electromagnetic simulator. Very good in my opinion, if you're into RF & Microwaves.
