7. (15 points) Linearly polarized wave incident on an air-conductor interface. A z-polarized uniform plane wave having an electric field with peak value 10 V/m and operating at 1.5 GHz is normally incident from air on a perfectly conducting surface located at y = 0, as shown below. (a) Write the phasor expressions for the total electric and magnetic fields in air. (b) Determine the nearest location to the reflecting surface in air where the total electric field is zero at all times. (c) Determine the nearest location to the reflecting surface in air where the total magnetic field is zero at all times. Perfect conductor (02=) y y=0 ON Air (€0, HO,01 =0) 8:04 ж.
