Моделювання оптичних структур методом кінцевих різниць у часовому просторі

Abstract

This paper deals with one of the most popular methods of numerical solution of electromagnetic problems – FDTD, which solves electric and magnetic fields in temporal and spatial domains and allows any geometry of model and imposes no restrictions on the properties of the material. The theoretical equations of electromagnetic information fields, when determining the values of waves and common problems in obtaining values in boundary conditions are studied. The proposed method of modeling curved surfaces between media allows to simulate surface electromagnetic and plasmon oscillations without additional losses of accuracy.
