A 3-GHz plane wave is incident from free space onto a lossless dielectric backed by a lossy dielectric as shown below. Determine the percentage of incident power that is dissipated in the lossy dielectric Normal Incidence on a Lossless and Lossy Dielectric A \( 3-\mathrm{GHz} \) plane wave is incident from free space onto a lossless dielectric backed by a lossy dielectric as shown below. Determine the percentage of incident power that is dissipated in the lossy dielectric.
