A TECHNIQUE FOR IMPLEMENTING THE FDTD ALGORITHM ON A NONORTHOGONAL GRID

A novel conformal FDTD technique is presented to accurately model curved metallic surfaces in 2D structures. This approach is easy to implement, is numerically stable, and yields results that are very accurate compared to the conventional staircasing method. © 1997 John Wiley & Sons, Inc.
