ferrite carcateristics

I need to simulate with CST a circulator with a ferrite inside. I am looking for an exemple having the caracteristics of a ferrite. That is ε, μ, tg (σ), ... etc

Thank you

you can look at ferroxcube.com. They are a producer of ferrites and have a lot of Data sheets available. so you can choose the one thats fits the best to your solution.

actually, the structure is supposed to be simulated at 2.5 GHz. And, I really have no idea of which example to choose. I looked at the list of products, and it seems that they are limited to 100 MHz, unless I am wrong

thank you once again

The specified frequency range for the most of the ferrites there is 30 - 1000 MHz. Actually I couldn't find a ferrite working at 2.5GHz on their page. I'm sorry.

go to Trans Tech Inc. they have lots of ferrite, magnet, dielectric material
