A special finite‐difference time‐domain (FDTD) formulation which allows electromagnetic (EM) wave wideband simulations of oblique incidence for periodic media is used for the design and analysis of an infrared photonic crystal filter with dual stopbands at 3–5 and 8–12 μm. The transmission coefficient in the main stopband (8–12 μm) is below −10 dB. Scattering coefficients are calculated for different incidence angles, and the stopbands are shown to exist for different angles of incidence. © 2000 John Wiley & Sons, Inc.
