| Abstract: | We present a new stratification method to analyse the characteristics of graded-index planar waveguides by multilayer with linear profiles.Test calculations are done for some index profiles with known solutions.In comparision with other approximate methods,our method is much more accurate,simpler and time saving,especially for close to cut off. |
