The treatment of geometrically small structures in FDTD by the modification of assigned material parameters [PDF]
A number of different improvements to the analysis by finite-difference time-domain (FDTD) of small structures, such as wires, strips and slots have been proposed in the literature.

Stable non-orthogonal FDTD method
Introduction: A number of techniques have been proposed to extend the classical Yee’s finite-difference time-domain (FDTD) algorithm to a grid that is conformal to curved objects. Such methods, including the nonorthogonal FDTD (NFDTD) [1, 2], can accurately represent the curved boundaries without resorting to inefficient staircase orthogonal meshes ...
