We demonstrate that branching of the electron flow in semiconductor nanostructures can strongly affect macroscopic transport quantities and can significantly change their dependence on external parameters compared to the ideal ballistic case even whe

In this article, we propose to discretize the problem of linear elastic homogenization by finite differences on a staggered grid and introduce fast and robust solvers. Our method shares some properties with the FFT-based homogenization technique of M

A range of composite materials that contain glass fiber reinforced polymers is inspected for various defects such as debonds, delaminations and foreign inclusions with a terahertz FMCW imaging system. The results are evaluated manually and by means o

In this study a validation of a novel NDT (non-destructive testing) technique is presented. The validation is carried out with Infrared Thermography, an established NDT tool for composite materials. Various Glass Fiber Reinforced Polymer samples with
