Patent ID: 8812252

Claim:
A system for analyzing an interaction between electromagnetic radiation and a material, the system comprising: a processing arrangement for executing computer programs; a display unit having at least one display screen; a memory unit that stores an application program that includes first executable instructions operable on the system for determining the interaction between the electromagnetic radiation and the material using at least one input from the display unit, said application program using at least one propagation equation and at least one rate equation and second executable instructions operable on the system for displaying a graphical user interface on the display unit, the second executable instructions including instructions to: show on the display unit a toolbox having a plurality of icons, the plurality of icons including at least a first icon representing a plurality of energy levels for the material and at least a second icon representing an element of a plurality of transition modules for the material, wherein the second icon has at least one associated numerical parameter used in at least one matrix included in the at least one rate equation; show on the display unit a designer window configured to present the plurality of energy levels for the material and the plurality of transition modules for the material; detect movement of a copy of the first icon from the toolbox to the designer window, thereby modifying within the designer window the plurality of energy levels, or detect movement of a copy of the second icon from the toolbox to the designer window, thereby modifying within the designer window the plurality of transition modules for the material; and receive the at least one associated numerical parameter for input into said at least one matrix of the at least one rate equation; and a storage unit that stores the results generated by the application program wherein the second executable instructions include instructions to show on the display unit one or a plurality of designer windows designed to present the plurality of energy levels for each composition in a composite material with at least two different compositions and the plurality of transition modules for each composition in the composite material with at least two different compositions.
