A plane electromagnetic wave with frequency f = 5 MHz is propagating in sea water ( e_r
= 72, m_r
= 1, and

 s =  4 S/m).  Find:

• the loss tangent


• the attenuation constant


• the phase constant


• the intrinsic impedance


• the phase velocity


• the wavelength


• the “skin depth”


• the distance for which the electric field decreases to 1% of its value at the surface
