WebNov 4, 2024 · S-Parameters Generalized If you want to get a formula for S11 for a particular circuit network, it’s best to look at the ABCD parameters. There is a universal formula for converting between ABCD parameters and S-parameters. Once you have the S-parameters for a channel, you can determine return loss using the formula shown above. Webalso provide an review of the relevant parameters of transmission-line theory. In Sec-tion 3 we review various frequency-dependent permittivity measurement methods for thin materials. We also study metal losses in various transmission-line structures. In Section 6, we present measurements on substrate and circuit-board materials. In
