Chapter 2. Modeling

This chapter explains how to perform a calculation using IMD.

Figure 2.1 is a picture of the main IMD window, or widget, in IDL terminology, as it appears when you start IMD for the first time. This widget consists of the following components: the menu bar, the STRUCTURE area, the DEPENDENT VARIABLES / INDEPENDENT VARIABLES / COUPLED PARAMETERS / FIT PARAMETERS area, the MEASURED DATA area, and the IDL Commands area.

The sections that follow describe how to use the main IMD widget in order to accomplish these tasks:

2.1 Designating materials and optical constants

2.2 Defining the structure

2.3 Specifying variables and coupled parameters

2.4 Performing the computation

2.5 Viewing, printing, and saving the results
