Novel highly accurate finite difference formulas for two-dimensional field computations in electromagnetics

     Novel highly accurate finite difference formulas (with accuracy higher than the 8th order) have been derived and used for two-dimensional field computations in electromagnetics. The finite difference formulas derivation is made under a power series expansion of the transverse electric or magnetic field components in the case of uniform rectangular discretization mesh. It has been shown that the use of derived FD formulas provide highly accurate solutions of physical problems which can be described with the two-dimensional Laplace’s equation.
      Derived finite difference formulas enable very cost-effective numerical field simulations and therefore they are ideally suited for implementation in CAD applications. Reported formulas have not been used in the finite difference method formulations in literature.
