Efficient interface conditions for the finite difference beam propagation method [PDF]
, 1992 It is shown that by adapting the refractive indexes in the vicinity of interfaces, the 2-D beam propagation method based on the finite-difference (FDBPM) scheme can be made much more effective. This holds especially for TM modes propagating in structures

Difference potentials method based on LOD splitting technique for nonlinear convection–diffusion equations with interfaces [PDF]
AUT Journal of Mathematics and ComputingIn this paper, we construct a difference potentials method (DPM) based on the locally one-dimensional (LOD) technique to solve the two-dimensional nonlinear convection-diffusion interface problems. The advantage of using the LOD scheme is that the linear

Modeling and simulation sedimentation process using finite difference method
Journal of the Mechanical Behavior of Materials, 2022 The goal of this research is to develop a numerical model that can be used to simulate the sedimentation process under two scenarios: first, the flocculation unit is on duty, and second, the flocculation unit is out of commission. The general equation of

Modal fields calculation using the finite difference beam propagation method [PDF]
, 1994 A method is described to construct modal fields for an arbitrary one- or two-dimensional refractive index structure. An arbitrary starting field is propagated along a complex axis using the slowly varying envelope approximation (SVEA).
