Development of Novel Material Models of Technical and Biological Structures for Electromagnetic Field Simulations in mm- and sub-mm-Wave Range

Project description

The aim of the research project is to develop novel material models for technical and biological structures. These models, which are based on mixing methods, are intended to fill the gaps in literature on dielectric material parameters (permittivity and conductivity) in the mm and sub-mm wavebands (about 30 GHz - 10 THz). As part of this research project, the acquired material data are then to be used for numerical computer simulations. In order to demonstrate the wide range of applications of these material models and also to show the limitations of the approach, two very different topics are covered: First, the electromagnetic exposure of human body tissues in current and future applications working at THz frequencies (sub-mm waves) is to be calculated and the suitability of the novel material models is to be evaluated. Second, high-resolution models of composite fiber materials with and without defects are to be developed and then irradiated with mm and sub-mm field sources. In this way, the field modifications in front of and/or behind the material samples as well as in the samples themselves can be compared in order to identify the causes for the observed misdiagnoses in non-destructive material testing with imaging techniques.
