  A new embedded model for curved thin panels is developed in the Transmission
Line Modeling (TLM) method. In this model, curved panels are first linearized
and then embedded between adjacent 2D TLM nodes allowing for arbitrary
positioning between adjacent node centers. The embedded model eliminates the
necessity for fine discretization thus reducing the run time and memory
requirements for the calculation. The accuracy and convergence of the model are
verified by comparing the resonant frequencies of an elliptical cylinder formed
using carbon fiber composite (CFC) materials with those of the equivalent metal
cylinder. Furthermore, the model is used to analyze the shielding performance
of CFC airfoil NACA2415.
