Efficient simulation of thin anisotropic conductive materials by using digital filter-based TLM method

In this paper, a digital filter technique is used for an efficient modelling of thin anisotropic conductive materials. Appropriate digital filter is developed to incorporate the scattering parameters of an anisotropic conductive panel allowing to include its presence without the need to model the panel thickness. The filter is implemented in the Z-TLM method. The example of carbon fibre composite material with frequency independent anisotropic electric conductivity is used to verify the accuracy and efficiency of the presented approach.
