PROJECT TITLE :
Extended Capability Models for Carbon Fiber Composite (CFC) Panels in the Unstructured Transmission Line Modeling (UTLM) Method
A good model of single- and multilayered thin panels, together with those fashioned using carbon fiber composite (CFC) materials, is incorporated into the transmission line modeling (TLM) methodology. The skinny-panel model could be a one-dimensional (one-D) one based on analytical expansions of cotangent and cosecant functions that are used to explain the admittance matrix within the frequency domain; these are then converted into the time domain by using digital filter theory and an inverse Z transform. The model, which is extended to allow for material anisotropy, is executed among one-D TLM codes. And, for the first time, the 2-dimensional (2-D) thin-surface model is embedded in unstructured three-dimensional (3-D) TLM codes. The approach is validated by using it to study some canonical structures with analytic solutions, and against results taken from the literature. It's then used to analyze shielding effectiveness of CFC materials in a very practical curved aerospace-related structure.
