IMD Overview

What's New in Version 4

Chapter 1. Getting Started

1.1 System requirements

1.2 Downloading IMD

1.3 Installing IMD

1.4 Starting IMD

Chapter 2. Modeling

2.1 Designating  materials and optical constants

• Browsing the IMD optical constants database
• Material designation method 1: by reference to an optical constants file
• Material designation method 2: by specification of density and composition

2.2 Definining a structure: specifying parameters

• Ambient
• Multilayer stack
• Layers
• Periodic multilayers
• Depth-graded multilayers
• Nested multilayers
• Layer-data files
• Substrate
• Interfaces
• Modified Fresnel coefficients: interface widths and interface profile functions
• Power-Spectral-Density functions
• Graded interfaces

2.3 Specifying variables and coupled parameters

• Dependent variables
• Specular optical functions / Electric fields
• User-defined specular optical functions
• Non-specular optical functions
• Independent variables
• Independent variables specific to electric field calculations
• Independent variables specific to non-specular optical functions
• Coupled parameters

2.4 Performing the computation

2.5 Viewing, printing and saving the results

• Saving the Results
• Viewing and Printing the Results - IMDXPLOT
• Fixed Curves
• Statistics: estimating film thicknesses, feature widgets, etc.
• Examples
• Reflectance and transmittance contours of a Y/Al multilayer
• Electric field intensitie contours of a Mo/Si multilayer
• Reflectance of a depth-graded C/Ni multilayer, using coupled parameters
• Normal incidence non-specular scattering for a Mo/Si multilayer using the BA
• Grazing incidence non-specular scattering for a W/Si multilayer using the DWBA
