Abstract
In the previous parts we considered the SIR as a distributed transmission-line resonator possessing a step-junction structure. When focusing on broad electrical characteristics to classify single-dimensional transmission-line resonators into homogeneous and inhomogeneous impedance resonators, the SIR can be categorized as an inhomogeneous impedance resonator. Thus, by expanding the basic concept of the SIR defined in the previous chapters, an expanded analysis method can be applied to inhomogeneous impedance resonators, such as tapered-line resonators possessing a continuous change in characteristic impedance. Although in the former discussions the step change in characteristic impedance is realized by a geometrical change in the structure of the transmission line, an equivalent impedance step can be achieved by altering the material applied to the transmission line, or by a combination of both structural and material changes.
