Extension of Compact TLM Air-Vent Model on Rectangular and Hexagonal AperturesAbstract
Compact transmission line matrix (TLM) air-vent model extension, to allow for a computationally efficient modelling of airflow arrays with rectangular or hexagonal apertures, even in the case of significant thickness of a supporting metal panel, is presented. An empirically derived model is introduced as an equivalent circuit into an otherwise coarse TLM mesh to account for the electromagnetic (EM) presence of apertures. The model accuracy and efficiency are validated on several characteristic electromagnetic compatibility (EMC) examples.
