CHAPTER IV
APPLICATION EXAMPLES
In this chapter, we present practical examples that demonstrate the use of the techniques developed in Chapter 2 (NFFFT) and Chapter 3 (TF/SF boundary) in the FDTD analysis of multilayered media. In the previous chapters, we considered examples that involved the method that is the subject of the respective chapter. For example, we only considered the far-field radiation from structures placed on half spaces and grounded slabs in Chapter , we only investigated the performance of the TF/SF boundary (namely, contain-ment of the incident plane wave, and transparency to the scattered wave) in Chapter 3. In this chapter, we bring into use both of the methods developed in Chapter 2–3; that is, the examples utilize both the TF/SF boundary, and the near-field-to far-field transform.
Scattering in Multilayered Media
In this section, we consider two problems that involve the scattering from perfectly con-ducting objects placed in a multilayered medium, when the incident field is a plane process of introducing the incident plane wave into the FDTD grid necessitates the use of the TF/SF boundary for multilayered media, while the calculation of the far-zone field scattered from the scattering object is done by the NFFFT. For this approach to be essful, the fields on the NFFFT box in Fig. 6 prise only the scattered is indeed the basic premise of the TF/SF boundary technique: allowing only the scat-tered field to exit the boundary. The mentioned transparency of the TF/SF boundary to the scattered wave was demonstrated in Section . The general configuration used for scattering problems in multilayered media is shown in Fig. 33. The TF/SF boundary contains the imperfections (or the scatterers) in the multilayered medium, denoted collectively as A. Field corrections are applied on the TF/SF boundary to create
