Polar May news: Gradient method (Beta) roughness model in Si9000e / SYTECH materials now in Speedstack libraries / EIPC Summer conference

1. Gradient method for insertion loss modeling added as a beta feature in Si9000e 23_05**. This method uses RMS roughness Rq for modeling the effects of copper surface on insertion loss. Contact polarcare@polarinstruments.com or your local office for an  update or evaluation.

Here are a few screenshots using the optional Si Projects feature to visualise how Gradient compares with legacy methods like  Hammerstad and Groisse.
3 methods compared:

Incrementing roughness:

Additional multi-line length graph support in Projects option:

2. SYTECH (Shengyi Technology) materials added to Speedstack on line libraries. Shengyi have delivered us a raft of updated  materials for Speedstack – to see which materials – and others are recently available please visit the Polar news page:
3. Imminent Date for your diary – EIPC Summer conference Munich Germany:

P.S. Any feedback or correlation studies with other tools using Gradient method is most welcome.

** For the security minded – Si9000e and Si8000m 23_05 also deploys FLEXlm v11.19.00
