| Сводка≠ | S-Parameters (Scattering Parameters) characterize RF and microwave networks by their transmission and reflection of voltage waves. Introduced by Kurokawa in 1965, S-parameters are ideal for high frequencies where wave effects dominate. Unlike impedance (Z), admittance (Y), or hybrid parameters, S-parameters are directly measurable with network analyzers, naturally account for characteristic impedance, and are intuitive for cascade analysis. S-parameters are the standard language of RF 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. |
