Design of a Nonlinear Taper Using SI Based Algorithms

Chapter
Part of the Studies in Computational Intelligence book series (SCI, volume 392)

Overview

Tapered transmission lines (tapers) are common means of transmitting power from one part/device to another part/device in many microwave and millimeter-wave devices. A taper are required to transform the output of a standard waveguide to oversized waveguide components. The design of taper should be carried out in such a way that the characteristic impedances at both the ends match. Two basic types of cross-section tapers are straight taper and variable (nonlinear) taper. In the straight taper, the taper angle is fixed throughout the length and abrupt discontinuities occur at both the ends, while in variable taper the taper angle is smoothly varied along the length of the taper. The advantage of a nonlinear taper is that the conversion of power to unwanted (spurious) modes is very less compared to straight taper [110]. In this chapter, the design and optimization of a nonlinear taper for use in a specific high power gyrotron is presented.
