Now we put a thin transparent polymer film onto the silver layer. Here we choose a very special kind of teflon, namely Teflon AF 1600 with n2 = 1.302 and k2= 1e-6. In this case the thickness is d2=2e-6 m = 2 um.
Five extrem sharp lines adds to the spectrum. In this case the resonance condition for the quasi waveguide or leaky wave guide is fulfilled.
