| Підсумок≠ | The Finite Integration Technique (FIT) is a numerical method for solving Maxwell equations on structured grids, formulating electromagnetics as a system of integral equations over grid cells. Introduced by Thomas Weiland in 1977, FIT bridges finite differences and finite elements, offering excellent accuracy, stability, and computational efficiency for a wide range of electromagnetic problems. FIT is the foundation of commercial solvers like CST Microwave Studio and is widely used in RF, microwave, and EMC engineering. | The Transmission-Line Matrix (TLM) method is a direct discretization of Maxwell equations using an equivalent transmission line network. Introduced by Johns and Beurle in 1971, TLM models electromagnetic fields as voltage and current waves propagating on coupled transmission lines. The method is intuitive, numerically stable, and efficient for both transient and frequency-domain electromagnetic problems. TLM remains competitive with FDTD and FIT for many RF and microwave applications. |
