The characteristics of guided waves scattered by nonuniform waveguide gratings are systematically investigated with the use of an equivalent network method. This procedure is based on a combination of the multimode network theory and the rigorous mode‐matching method. Concave Bragg gratings and bent waveguide gratings are taken as examples to demonstrate the present approach, and numerical results are given to illustrate their potential for millimeter‐wave and optical integrated circuit applications. © 1997 John Wiley & Sons, Inc.
