Hello,

I am simulating characteristic impedance for multi-layer substrates on momentum. How do you set up to calculate the effective dielectric constant?

Thanks

Sam

epsr_eff=(3e8*imag(GAMMA(1))/(freq*2*pi))**2

GAMMA(1) refers to port 1 and this should give you an array as a function of frequency for effective dielectric constant.
