Conversion between the TLM solutions and field solutions

The Transmission-Line Matrix (TLM) method uses a network of interconnected transmission lines to simulate electromagnetic wave propagation. Therefore, the TLM solutions are not exactly the field solutions, especially for two-dimensional cases. As a result, conversion between the TLM solutions and field solutions need to be described. This issue is addressed in this paper and boundary (interface) conditions for the two-dimensional (2D) TLM dual mode simulations are formally derived. Also, the correspondence between simulated constitutive parameters and those of the actual medium is formally established.<
