Improved approximate scalar finite-element analysis of optical waveguides
The match conditions of wave vector is firstly used for solving the strip waveguide problems by approximate scalar finite-element method in this paper. Thus the two-dimensional problems are simplified into two one-dimensional ones. This may provide a new approach for less computer memory and time, and retains all the advantages of approximate sealan finite-element method.
