Two lossy dielectric media with permittivities and conductivities (ε1​,σ1​) and (ε2​,σ2​) are in contact. An electric field with a magnitude E1​ is incident from medium 1 upon the interface at an angle α1​ measured from the common normal, as in Fig. 5-10. FIGURE 5-10 Boundary between two lossy dieloctric media (Problem P. 5−9). a) Find the magnitude and direction of E2​ in medium 2 b) Find the surface charge density at the interface c) Compare the results in parts (a) and (b) with the case in which both media are perfect dielectrics.
