Capacitor Impedance Evaluation from S-Parameter Measurements

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.

High Intensity Radiated Fields (HIRF), Part 2

The evolution of HIRF (High Intensity Radio Frequency) testing standards was driven by "fly-by-wire" aircraft vulnerabilities. From 1989, test requirements jumped dramatically from 1-2 V/m to 200 V/m, prompting extensive research and new guidelines for protecting aviation electronics.

Was it the Radar? Respectfully Revisiting the 1967 US Navy USS Forrestal Carrier Disaster: Part 1

In 1967, one of the U.S. Navy's worst peacetime disasters occurred aboard the USS Forrestal aircraft carrier off Vietnam's coast. A weapon misfire triggered a devastating chain of explosions and fires, resulting in hundreds of casualties and nearly destroying the ship.

EMC Testing of E-Motor Systems

Explore essential strategies for EMC testing of electric axles in automotive applications. This technical guide examines key challenges in achieving CISPR 25 compliance, from test bench design to managing metallic structures, while ensuring accurate and reproducible measurements for high-power e-drive systems.

Analysis of Transmission Lines in Sinusoidal Steady State: Part 3

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.
