A uniform plane wave propagating in a medium has
if the medium is characterized by ϵr = 1, μr = 20 and σ = 3 S/m. The value of α and β are respectively.
When an electromagnetic wave is incident on an object having surface roughness comparable to the wavelength, then:
The velocity of a wave travelling in the air medium without transmission lines or waveguides(wireless) is
The phase shift in the electric and magnetic fields in an EM wave is given by which parameter?
