Exercise 36

A perpendicularly polarized uniform plane wave in air of frequency f is incidentobliquely at an angle of incidence i; on a plane boundary with a lossy dielectric mediumthat is characterized by a complex permittivity 2 = ' - j ". Let the incident electric field be

a)Find the expressions of the transmitted electric and magnetic field intensity phasorsin terms of the given parameters.
b) Show that the angle of refraction is complex and that H t is elliptically polarized.
