Two-dimensional TE Series Node Transmission-Line Modelling Based on Unstructured Triangular Meshes

The transmission-line modelling (TLM) method has been widely applied to many areas of electromagnetic simulations. This paper presents the development of the series TE model for the TLM method based on triangular meshes. The 2D series unstructured TLM is validated using the case of the metallic cylindrical resonator and applied to the field analysis on photonic nanotip tapers.
