The B-spline finite element based parabolic wave propagation inside a parallel plate waveguide
A b-spline based finite element method parabolic wave propagation model is developed and tested against mode summation inside a parallel plate waveguide. The comprehensive numerical analysis of the solution of parabolic wave equation has been done. The algorithm is compared with mode summation in two dimensions. Excellent agreement is observed among the results.  2013 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2013.
