Abstract : The hitherto used BPM algorithm based on the MoL was first demonstrated at the Hilton Head Conference and than described in. The MoL-BPM overcomes the disadvantages of the BPM based on the paraxial approximation, e.g. small refractive index steps, artificial absorbers, numerical loss. Special characteristics of the MoL-BPM are the use of Helmholtz (or Sturm-Liouville) Equation, numerical absorbing or radiation conditions, use of eigensolution, implementation of the interface conditions for the fields. In this contribution two new algorithms will be presented. First a special algorithm for waveguide bends is presented. Then an algorithm for the vectorial field is described.
