Total internal reflection occurs when the magnitude of the wave vector in air is smaller than the required wave vector component along the surface. When light propagates by total internal reflection TIR through an optical fiber or a planar optical waveguide a small portion of the electromagnetic wave penetrates the region of lower. Power flow and the Poynting vector.

Write expressions for the reflected and transmitted electric and magnetic fields for the case of θ θc where the. 1 then the phenomenon known as total internal reflection can occur. The energy flux density ie the rate of energy transmission per unit area is called.

Poyntings theorem describes the fate of power entering a region V consisting of materials and structures capable of storing and dissipating energy. When we have total internal reflection of light at the boundary of an optically dense to an optically thinner medium one can show that the component of the Poynting vector.
