Quote:

phi_c = (phi1*Y1*d1 + phi2*Y2*d2 )/ (Y1*d1 + Y2*d2)    --------(1)

This formula is only sensitive to the ratio YL/YH (which I've called E1/E2).

I took the parameters from Penn, chose two fiducial coating thicknesses (a λ/4 + λ/4 coating, and a 3λ/8 + λ/8 coating), and used this (along with Penn's reported values for E1, E2, φ1, and φ2) to compute two fiducial values for φc. Then I solved these two equations for φ1 and φ2, and allowed them to vary parametrically with the ratio E1/E2.
