A uniform plane wave in air with E i ( z ) = a x 10e j 6 z (V/m) is incident normally on an interface at z = 0 with a lossy medium having a dielectric constant 2.25 and a loss tangent 0.3. Find the following:
a) The phasor expressions for E r ( z ), H r ( z ), E t ( z ), and H t ( z ).
b) The standing-wave ratio for the wave in air.
c) The expressions for time-average Poynting vectors in air and in the lossy medium.
