Milo Hyde

What are you given in the problem?

Khalid Al-badri

Dear Dr. Milo Hyde

I have S11 and S21 for metamaterial absorber I want to find negative permittivity and negative permeability

Use Nicolson, Ross, Weir (NRW). It's an algebraic approach which solves for permittivity and permeability in terms of S11 and S21.

Abdelaziz Qarchi

La relation de NRW relie les paramètres S a la permittivité et la perméabilité dans les conditions d’homogénéisation.
