Performance-Based EMC Design Using a Maximum Radiated Emissions Calculator

Abstract

Meeting electromagnetic compatibility (EMC) requirements can be a significant challenge for engineers designing today's electronic devices. Traditional approaches rely heavily on EMC design rules. Unfortunately, these design rules aren't based on the specific EMC requirements for a particular device, and they don't usually take into account the specific function of the circuits or the many design details that will ultimately determine whether the device is compliant. This paper describes a design methodology that relates design decisions to the product's EMC requirements. The goal of performance-based EMC design is to ensure that electronic designs meet EMC requirements the first time the product is tested. More work needs to be done before this concept reaches its full potential, but electronic system designers can already derive significant benefit by applying this approach to products currently under development.

Analysis of electromagnetic interference under different types of near‐field environments

“…1. According to the increase of α, Z e increases from 51.5 to 76 dBΩ, but Z m decreases from 51.5 to 27 dBΩ, which agree well with (3). Noting that free space wave impedance is 51.5 dBΩ (indicated by blue broken lines), our waveguide develops electric and magnetic NF environments very well.…”

“…However, many EMC issues are not confined to only far‐field problems. In practice, many electronic devices coexist in a relatively small area belonging to a near‐field (NF) region, which should also be carefully considered in modern EMC tests [3]. To configure a NF‐like environment, several methods of manipulating wave impedance inside TEM waveguides have been reported [4–6].…”

Validation of Compact-Standard Antenna Method for Antenna Calibration above 1 GHz

“…This increase has created a complex propagation environment, which has expanded the electromagnetic interference (EMI) problem. Internationally, to distribute electric and electronic equipment on the market, companies must obtain electromagnetic compatibility (EMC) certification [1,2].…”
