In this Letter a unified nonuniform cylindrical finite‐difference–time‐domain (NU‐CFDTD) algorithm is utilized for the analysis and design of cylindrical millimeter‐wave integrated circuits (CMICs). It is shown that the algorithm is efficient in coding and flexible in treating various materials and discontinuities without adding computational resources compared with the traditional FDTD method. A visual mesh generator, CylinMesh , is developed to generate nonuniform meshes and input parameter files for practical cylindrical MIC analysis and design. © 2002 Wiley Periodicals, Inc.
