It has two components, Electric field E and Magnetic field M, both perpendicular to the direction of propagation Electromagnetic energy radiates in accordance with the basic wave theory. This theory describes the EM energy as travelling in a harmonic sinusoidal fashion at the velocity of light.

people.brunel.ac.ukelectromagnetic field configurations. For monochromatic light fields of radian frequency ω, a mode travelling in the positive z direction has a time and z dependence given by •The factor β is the z component of the wave propagation constant k=2π/λ. For guided modes, βcan assume only certain discrete values. ej(ωt−βz)
