Resumen	Load-Pull is an experimental technique for characterizing and optimizing RF power amplifier performance under varying load and source impedance conditions. Introduced by Davidson et al. in 1990, load-pull measurements vary the load impedance seen by the amplifier while recording output power, efficiency, and linearity. Load-pull reveals contours of constant gain, efficiency, and stability, enabling optimal impedance matching for maximum performance. Essential for power amplifier design and characterization.	The Method of Moments (MoM) is a powerful numerical technique for solving electromagnetic boundary integral equations derived from Maxwell equations. Pioneered by Roger Harrington in 1968, MoM discretizes only radiating surfaces and boundaries (antennas, conductors, dielectrics), not the surrounding space, making it efficient for radiation and scattering problems. MoM remains the standard tool for antenna design, electromagnetic compatibility analysis, and RF/microwave engineering.	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.
