Abstract in another language

The quantitative determination of material parameter distributions in resonant cavities is a relatively new method for the real-time monitoring of chemical processes. For this purpose, electromagnetic resonances of the cavity resonator are used as input data for the reverse calculation (inversion). However, the reverse calculation algorithm is sensitive to disturbances of the input data, which produces measurement errors and tends to diverge, which leads to no measurement result at all. In this work a correction algorithm based on the Monte Carlo method is presented which ensures a convergent behavior of the reverse calculation algorithm.

Abstract in another language

Die quantitative Bestimmung von Materialparameterverläufen in Hohlraumresonatoren ist eine relativ neue Methode zur echtzeitfähigen Überwachung verfahrenstechnischer Prozesse. Dazu werden elektromagnetische Resonanzen des Hohlraumresonators als Eingangsdaten für die Rückrechnung (Inversion) verwendet. Der Rückrechenalgorithmus ist allerdings empfindlich auf Störungen der Eingangsdaten, die zu Messabweichungen führen und neigt zum Divergieren, was zu gar keinem Messergebnis führt. In dieser Arbeit wird ein auf der Monte-Carlo-Methode beruhender Korrekturalgorithmus präsentiert, der für ein konvergentes Verhalten des Rückrechenalgorithmus sorgt.
