Abstract

The possible design of phase shifters with reduced frequency dispersion using combined sections of forward‐wave (FW) and backward‐wave (BW) transmission lines is discussed. It is shown that inclusion of backward‐wave sections into a transmission line always increases the total dispersion. On the other hand, we show that dispersion can be reduced by means of lines with positive anomalous dispersion and provide an example of such line. Β© 2005 Wiley Periodicals, Inc.

We consider a single-input single-output nonlinear system which has a well-de"ned normal form with asymptotically stable zero dynamics. We study the design of a robust output feedback controller that incorporates a linear servo compensator to achieve asymptotic tracking and disturbance rejection. We
