In this chapter, enlargements of the more frequently used regions of the SMITH CHART will be presented and discussed, and special applications for these will be given. The graphical representation of the properties of stub sections of waveguide which are operated near their resonant or antiresonant frequency, as may be readily portrayed on two of these expanded charts, will be discussed in some detail.
