Communications with Low Frequencies (LF) and Very low frequencies (VLF) are used for military purposes, specially for communicating worldwide with submarines underwater at shallow depths. The modeling and simulation of such antennas require numerical methods close to their validity limits. The subject of this thesis deals with the global...

The purpose of this paper is to develop a modeling tool for VLF/LF antennas taking into account surrounding components such as insulators. Numerical results of the field distribution along an insulator using the transmission line method (TLM) are pesented. These results are compared with commercial software data and show a good agreement. A...

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...
