A New Approach to the Modeling of Anisotropic Media with the Transmission Line Matrix Method

A reformulation of the Transmission Line Matrix (TLM) method is presented to model non-dispersive anisotropic media. Two TLM-based solutions solve this problem can already be found in literature, each one with an interesting feature. One considered a more conceptual approach, close TLM fundamentals, which identifies Maxwell’s equations specific line. But simplicity achieved at expense increase memory storage requirements general situation. The second existing solution powerful and formulation that avoids storage. However, it based on signal processing techniques considerably deviates from original method, may complicate its dissemination scientific community. work exploits benefits both methods. On hand, maintains direct approach TLM, help better understand it, allowing for future use improvement by other authors. proposal includes optimized treatment signals stored stub lines order limit requirement only accumulative term per field component, as versions used isotropic good behavior proposed algorithm when applied media shown application different situations involving diagonal off-diagonal tensor properties.
