In this paper, a number of photonic band‐gap (PBG) structures, which are formed by periodic circuit elements printed on transmission‐line circuits, are studied by using a well‐known numerical method, the finite‐difference time‐domain (FDTD) method. The results validate the band‐stop filter behavior of these structures, and the computed results generally match well with ones published in the literature. It is also found that the FDTD method is a robust, versatile, and powerful numerical technique to perform such numerical studies. The proposed PBG filter structures may be applied in microwave and communication systems. © 2004 Wiley Periodicals, Inc.
