The establishment of a rigorous full-wave eigenanalysis based on finite element method as numerical tool for the understanding and the revealing the characteristics of Terahertz nano-antennas, constitutes the scope of the current work. A tree-cotree splitting formulation method is incorporated for the suppression of all types of spurious modes. An indicative example of a gold nanodimer structure is...
A novel concept of collocation method is introduced and used for the first time to obtain a simple and accurate solution for the boundary layer in unbounded domain. Similar analysis is however not available yet in the literature. The idea is to transform the equations and boundary conditions into another set of variables and also to augment an extra boundary condition. To demonstrate the effectiveness...
