-The electric field and magnetic field in free space are given by 50 E = cos(10°t + Bz) ap V/m ρ H = Ho cos(105t + Bz) ap A/m Express these in phasor form and determine the constant H, and ẞ such that the fields satisfy Maxwell's equations. -The instantaneous form of E and H are written as: E = Re(Esejwt), (1,1) H = = Re(Hsejwt), (1,2) W = 106 The phasor E, and Hs Es = 50 jẞz aq ρ (1.3) (14) Ho H₁ = Neiz ap P For free space p = 0,σ = 0,ε = εo,μ = μo so Maxwell's equations become V.Es=O (1.5)
