Figure 3

Comparison between simulated and experimental absorbance spectra as a function of the azimuthal angle φ with different polyimide loss tangent values under 16° oblique incidence in TE polarization. The simulations have been performed with the complex permittivity value (a) ε r  = 2.9 − 0.0058 j and with the estimated complex permittivity value (b) ε r  = 2.9–0.25 j for the polyimide layer.
