✦ Synopsis

A method to design a tapered transmission line with desired beha¨ior in the reflection coefficient and with a smooth impedance transition from the feeding line to the load is presented. The method optimizes an objecti¨e function through the simulated annealing technique by perturbing the roots associated with the expression of the approximated reflection coefficient. The obtained results show the capabilities of the method in reducing the percentage of loss of the taper length, and also in impro¨ing the smoothness of the final characteristic impedance.

An iterati¨e 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.

## Abstract It has been shown recently in the literature that the conjugately characteristic‐impedance transmission lines (CCITLs) implemented by periodically loaded lossless lines can exhibit active characteristic impedances (i.e., negative characteristic resistances). In this case, the magnitude

## Abstract The bi‐characteristic‐impedance transmission lines (BCITLs) are generally lossy transmission lines that possess different complex characteristic impedances for waves propagating in forward and reverse directions. Because of complicated equations associated with BCITLs, a graphical tool
