emc concepts explained

This is the first of seven articles devoted to the topic of shielding to prevent electromagnetic wave radiation. The results presented here are valid under the assumption of a uniform plane wave with normal (perpendicular) incidence on a boundary between two media.

This column examines inductor impedance evaluation using S₂₁ parameters with network analyzers. Comparing two-port shunt and series methods across multiple inductors, it concludes that the two-port series method provides significantly more accurate measurements when compared with manufacturer data.

This first installment in a two-part series evaluates inductor impedance using S11 parameters across one-port shunt, two-port shunt, and two-port series methodologies. Experimental results reveal significant discrepancies between measured values and manufacturer specifications, highlighting limitations in S11-based impedance characterization techniques.

This article explores S₂₁ parameter methods for measuring capacitor impedance. Comparing two-port shunt and series techniques with established benchmarks reveals the two-port shunt method delivers superior accuracy across multiple capacitor values and frequency ranges.

Ever wonder how accurate your capacitor measurements really are? This deep dive into network analyzer techniques compares three different methods for measuring impedance, uncovering surprising limitations in standard s₁₁ parameter approaches that engineers should know about.

This is the third and final article discussing four different circuit models of transmission lines in sinusoidal steady state. This article uses Model 4 to determine the locations of the minima and maxima of standing waves. This determination is first done analytically, followed by the graphical method using the Smith chart.

This column continues a series on transmission line circuit models, exploring two additional models. It derives equations for voltage characteristics and standing waves, building upon concepts introduced in the previous installment.

This article discusses two of four circuit models for transmission lines in sinusoidal steady state. Model 1 is used for solving equations, while Model 2 introduces standing waves. The author explains their applications and differences.

This article explains how to use a Smith Chart to determine the voltage standing wave ratio (VSWR).
