A dielectric slab of polystyrene (, = 2.56), of any thickness, is bounded on both of its sides by air. In order to eliminate reflections on each of its interfaces, the slab is cov- ered on each of its faces with a dielectric material. At a frequency of 10 GHz, determine, for each dielectric material that must cover each of the faces of the slab, the: (a) Thickness (in ;; wavelength in the cor- responding dielectric). (b) Thickness (in cm). (c) Dielectric constant. (d) Intrinsic impedance of its medium. (e) SWR created in air when a plane wave impinges at normal incidence from one of its sides when the slab is covered with the selected cover material.
