A new 3-D TLM-TW (Transmission Line Matrix - Twin Wire) numerical scheme is proposed for modeling thin wires buried in a general inhomogeneous, dispersive, conductive medium. To solve the time convolution product introduced by the dispersive medium, a recursive algorithm obtained by bilinear Z-transform approach is used. This technique is...
Un modèle de fil mince arbitrairement orienté pour le maillage cartésien 3D TLM est présenté. Il permet de tenir compte des jonctions ainsi que du couplage de proximité entre plusieurs fils. Les comparaisons entre les simulations et les mesures d'antennes filaires typiques valident le modèle.

In this paper, a validation of the proposed technique is provided through comparisons between simulated, theoretical and measured results for wire patch antennas and loaded dipoles. The capability of this technique to simulate a VLF/OMEGA antenna is also demonstrated.The technique presented in this paper is suitable to analyze multi-scale...
