Dear Mr Gyorgy Banhegyi, I'd like to thank you very much for your reply and for all the attached links and papers.

That's exactly what I'm looking for, the corona modelling for the calculation of transient. It will help me in my research project.

Best regards,

Omar

You can find much more easily with Google

Oh! OK, I think that I had chose wrong keywords in my web search.

Thank you again
