This article discusses the common-mode and differential-mode radiation from cables and presents the measurement results from the SMPS connecting wires.

This article discusses the basics of a step-down (buck) DC Switched-Mode Power Supply (SMPS). It should serve at an entry-level tutorial and a building step towards the more advanced designs.

Part II of this two-article series focuses on log-periodic and biconical antenna impedance, VSWR, and radiated emissions measurements.

This two-article series is devoted to a dipole family of antennas used in EMC testing: half-wave dipole, quarter-wave monopole, log-periodic, and biconical antenna.

This article discusses the origins, justification, and interrelations between some of basic EMC rules regarding the highest significant frequency (bandwidth) present in digital signals, definition of the electrically short structures, and the transmission line criterion.

We investigate two four-layer PCBs with power and ground plane pairs spaced 3 mils and 30 mils apart.

We investigate two four-layer PCBs with power and ground plane pairs spaced 3 mils and 30 mils apart.

This tutorial article focuses on the skin depth phenomenon in good conductors. We begin with the uniform plane propagation, leading to the wave equations and their solutions in different media.

In this article the performance of the π and T filters is evaluated and compared to that of the CL and LC filters.

This column discusses the second- and third-order low-pass EMC filters.
