An iterative method for the design of tapered transmission lines is described. The method applies the Fourier transform to a linearized Riccati equation to yield a spectral function Q ( k ) which relates to a frequency spectrum with a corresponding characteristic impedance profile. Numerical results show that the spectral function and the calculated spectrum improve with iterations. The method also removes discontinuities in impedance profiles, and can be applied to design impedance‐matching circuits and microwave filters with arbitrary passband characteristics. ©1999 John Wiley & Sons, Inc.
