Field and Wave Electromagnetics 2nd Edition by David Cheng

تمرين 1

Two lossy dielectric media with permittivities and conductivities ( 1 , 1 ) and ( 2 , 2 ) are in contact. An electric field with a magnitude E 1 is incident from medium 1 upon the interface at an angle 1 measured from the common normal, as in Fig.
a) Find the magnitude and direction of E 2 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.
