WebThe modes that propagate in a fiber are found by solving Maxwell's equation for the electric field of the light in the fiber in cylindrical coordinates. Solutions which are harmonic in space and time, are of the form E (r,φ,z) = f (r) cos (ωt - βz + c) cos (qφ) where ω is the angular frequency of light and β is the propagation constant. WebFigure 4: Finite Difference uniform mesh. Formally, we have from Taylor expansion: Subtracting Equation 51 from Equation 51 and neglecting higher order terms: Thus, for TE modes we get.
