Unknown medium. The magnetic field phasor (i.e., time-harmonic form) of a 100MHz uniform plane wave in a nonmagnetic medium is given by Hₛ (z)​=x^3eʲ⁽¹⁷⁻ʲ¹⁰⁾ᶻ A/m (a) Find the conductivity σ and relative permittivity εᵣ of the medium. (Hints: Substituting α and β in their corresponding equations and taking the square of the ratio of these two equations, and you can solve σ )
