I really like QUCS (recently downloaded) and looked at the roadmap for the product.
Related to this, I have some thoughts regarding EM Field Simulator:
- I am using a combination of static field solver http://www.fastfieldsolvers.com/, and s parameter math that takes into account input frequency to generate s-parameter matrix of the ports.
- One question related to this: Did you want Dxf import ability as a part of the EM simulator package for this tool (similar to ADS)?
