A parallel-pole electromagnetic wave with a frequency of 10 kHz comes from the air towards the ocean surface, with an angle of incidence θi = 81 °. Here, since the electrical properties of ocean water are ?? = 81, ?? = 1, ? = 4;

a) Find θt refraction angle, ? || the penetration coefficient and the ocean depth where the electric field intensity decreases by 30 dB.

b) If a perpendicular polar electromagnetic wave from a source below the ocean to the air came to the water-air interface with θi = 20 °; What would be the critical angle θc?
