Development and evaluation of biological and technical material models for numerical simulations of the human body's exposure to Terahertz fields, respectively of non-destructive testing analyses of glass- or carbon-fibre reinforced structures with mm- or

该项目的主要目的是开发新的技术和生物结构材料模型。建立在“有效介质理论”基础上的这种模型被认为是为了弥补文献中关于毫米波和亚毫米波(约30 GHz至10太赫兹)介电材料参数(介电常数和电导率)的现有空白。在该项目的范围内，这样获得的数据将用于计算机数值模拟。为了展示材料模型的应用范围，也为了确定程序的局限性，应处理两个非常不同的主题领域：一方面，人体组织应暴露在太赫兹频率(亚毫米波)的电磁照射下，以评估新材料模型的适用性。另一方面，应开发具有和不具有局部缺陷的纤维增强复合材料的高精度模型，并由毫米和亚毫米源进行照射，以便比较测试结构之前和/或之后以及材料模型内的现场修改。这是为了能够分析在成像系统的基础上报告的与无损检测有关的诊断缺陷的原因。

Primarily, the project aims at the development of new material models of technical and biological structures. Such models to be created on the basis of an "effective medium theory" are supposed to close the existing gaps in the literature concerning dielectric material parameters (permittivity and conductivity) in the mm- and sub-mm-wave region (ca. 30 GHz to 10 THz). Within the scope of the project, the thus obtained data are then to be used in numerical computer simulations. In order to demonstrate the breadth of applications of the material models, but also to work out the limits of the procedure, two very different subject areas shall be treated: on the one hand human tissue shall be the electromagnetically exposed at THz frequencies (sub-mm waves) to assess the suitability of the new material models. On the other hand, high-precision models of fibre reinforced composite materials with and without local defects shall be developed and irradiated by mm- and sub-mm sources, in order to compare field modifications in front of and/or behind the test structure, but also within the material models. This is to enable an analysis of the causes of deficient diagnoses which were reported in connection with the non-destructive testing on the basis of imaging systems.
