• Cvector Ap, Bp, Cp, Dp, Am, Bm, Cm, Dm
  Cvector ap, bp, cp, dp, am, bm, cm, dm
  Following variables (and their notations) are based on the model of MR presented by Manfred in the NAIS document dated Sept. 12'th, 2002.
  size of these matrices is determined by no. of modes of bend waveguide and straight waveguide. See constractor() for details. p/m= plus / minus
