Hiiii guys,
I had already posted my query but none responded, I guess you'll did not understand my question. I repeat myself once again,
I want to plot phase constant beta (β) Vs magnetic bias (dc bias), for this I have plotted theoritically, but practically, I'm using a simple 52 mm long and 0.7mm wide stripline on a ferrite substrate of permittivity 14, I'm simulating it for different magnetic bias, now I don't know how should I find phase constant beta out of what results?, I mean I have to plot phase constant beta against magnetic bias and compare it with theoritical plot, so if anyone can guide me in how should I find beta using the data table, my simulation gives me S11, S12, S21, S22 along with magnitude, and phase of each at different frequencies,
plzz tell me am formula or method of finding beta.
Thanx in advance.

β=φ/L
φ=arg(S12) or arg(S21) - phase shift
L= 0.052 - length of waveguide (check that L < λ - wavelength in the waveguide)
