1. Consider two dielectric slabs; one is polystyrene (er 2.56, r = 1) == and the other is silicon (e, 11.9, 1). Plots of the transcendental equations for both dielectrics and for both TE and TM modes are provided on separate sheets. For this problem we are interested in frequency 100 GHz and slab thickness 2h=380m. (a) (5 points) Why are there two plots (red and blue curves) for TM modes whereas a single plot (black curves) for TE modes? (g) (5 points) Describe how ayo affects the fields associated with a dielectric slab.
