22.1 Introduction

In this chapter we consider the program for calculation of the electromagnetic properties of the multilayered microsphere. Such a program is more complicate compared to the spontaneous emission program. The physics of this problem is explained in Secs. 1.3, 1.4 and 1.5. In Figs. 22.1, and 22.2 the structure of classes is shown. So far as the program code of this problem is too long, it can be found in the web site, indicated in the Introduction to this book.

In Fig. 22.3 the graphical user interface, which was created in Borland C++ Builder (bcb), is shown. In the TabSheet named "WORK" (see Fig. 22.3) one can put the parameters most frequently used while calculating. They are the number of layers, the structures of layers, the spherical quantum number, number points to plot, TE or TM modes are examined, etc. Some of the accessible operations are specified. In Figs. 22.4 and 22.5 the typical examples are shown. Figure 22.4 shows the frequency dependence of the reflection and transmittance coefficients, whereas Fig. 22.5 shows the radial distribution of both electric and magnetic optical fields in the microsphere and spherical stack.
