Zusammenfassung der Projektergebnisse

To summarise this report we like to outline the most important goals achieved during the first part of the project: • Both DSM and NFM-DS were extended to simulate TIRM calibration curves. • The simulation tools were validated by comparing of the simulation results to each other. There was a good agreement. • The simulation methods were validated by comparing to measurement results. Close agreement was achieved. • We were able to demonstrate that oscillations in TIRM calibration curve were caused by particle-prism scattering interaction. • The DSM TIRM model has been extended to coated spheres and a multi-layered plane interface.
