This paper presents the measurement results of a electric-dipole-based-parasitic-element array optimized for gain, taking into account the loss resistances derived from full-wave simulation. The high gain reached (8.6dBi for a ka of 1.4) show the interest of this optimization method presented in an earlier work, maximizing intrinsic gain rather...

Une nouvelle formulation des fils arbitrairement orientés dans le maillage TLM est proposée. Le nouveau modèle satisfait le principe de conservation de la charge favorisant le couplage fil-maillage sur une seule cellule. Il repose sur un schéma numérique explicite désynchronisé et permet de tenir compte d'interconnexions entre plusieurs fils.

This article presents the mathematical model of the unconditionally stable explicit transmission-line matrix (USE-TLM) method, which can operate at a time step beyond the Courant–Friedrichs–Lewy (CFL) limit. This technique is based on the eigenmode decomposition of the system matrix that represents the computational domain. Then, by eliminating...
