The plane wave solution depends on the _________Select one:a. properties ε, μ, σb. properties of the medium and frequency rangec. frequency ranged. attenuation constant and phase constant

In free space E (z,t) = 50 cos(wt -gz) a, (V/m). Find the following.1) Intrinsic impedance of the medium.2) State the direction of the electromagnetic3) Find a magnetic field vector.4) State the poynting vector equation.5) Comment on attenuation constant.

he electromagnetic wave travels in a medium at a speed of 2.0 × 108m/s. The relative permeability of the medium is 1.0. The relative permittivity of the medium will be:

A plane electromagnetic wave travels in a medium of relative permeability 1.6 and relative permittivity 6.44. If magnitude of magnetic intensity is 4.5 × 10–2 A m–1 at a point, what will be the approximate magnitude of electric field intensity at that point? (Given: permeability of free space  μ0  =  4π × 10−7​N​A−2, speed of light in vacuum c = 3 × 108 m/s)

If εr = 9, µ=µ0 for the medium in which a wave with frequency f= 0.3GHz is propagating, calculate propagation constant, intrinsic impedance and phase velocity of the medium when i) σ =0 and ii) σ= 10 mho/m
