An analysis of the higher‐order modes in open microstrip lines is presented based on the finite‐difference‐‐time‐domain (FDTD) electromagnetic simulation in conjunction with the joint time‐frequency processing of the resulting data. The wavelet transform is applied to the simulation data to distinguish the various higher‐order modes in the joint time‐frequency plane. Then, a technique that extracts the field information at a unique time‐frequency point is used to construct the spatial field distribution of each mode. © 1996 John Wiley & Sons, Inc.
