GATE Question Of The Day – Electromagnetics

The electric and magnetic fields for a TEM wave of frequency 14 GHz in a homogeneous medium of relative permittivity e_r and relative permeability m_r =1 are given byV/mA/mAssuming the speed of light in free space to be 3 ´ 10⁸ m/s, the intrinsicimpedance of free space to be 120p , the relative permittivity e_r of the medium and the electric field amplitude E_p are

(A) e_r = 3, E_p = 120p

(B) e_r = 3, E_p = 360p

(C) e_r = 9, E_p = 360p

(D) e_r = 9, E_p = 120p
