Many optical and electromagnetic applications involve large thin plates, which include planar waveguides, diffractive optical elements, photo masks, filters, and so forth. Typically, those structures have a relatively small thickness and a very large surface. Three‐dimensional (3D) simulation of those thin plates using FDTD, which requires a large sampling rate, is sometimes unpractical due to the memory requirement. In this paper, we investigate 3D simulations of electrically large thin plates using the hybrid PSTD‐FDTD method. As an example, we study the near‐field scattering of a photo mask and compare the hybrid method with the FDTD method. © 2005 Wiley Periodicals, Inc.
