Abstract: The basic formulations used in the description of thin walls and small apertures in simulations based on the Transmission-Line Modelling (TLM) method are described. It is shown that efficient and accurate methods are available which exhibit a reasonable balance between accuracy and computational efficiency. Results of simulations are presented showing the shielding effectiveness of cabinets.
Keywords: Transmision line modeling, electromagnetic compatibility, shielding, simetrical condensed node.
