EMC/EMI

An increasing number of manufacturers are adding or retrofitting wireless technology into new or existing products. These products typically include mobile, household, industrial, scientific, and medical (ISM) devices. This transition towards “everything wireless” is in full swing, and with it comes problems with electromagnetic interference (EMI) from the product itself interfering with sensitive on-board cellular, GPS/GNSS, and Wi-Fi/Bluetooth receivers. Read on to find out what to do about it.

SIJ had the opportunity to engage with Larry Williams, ANSYS director of technology, to find out his thoughts on how modeling and simulation needs have changed, how the industry has responded, and what’s next. At ANSYS, Larry Williams is responsible for the strategic direction of the company’s physics simulation products.

One decision launched Todd Hubing on his current career path and has had a profound impact on the direction the EMC industry has taken over the last 35 years. Here's a summary of my interview with Todd.

On the first day of the 2019 IEEE EMC Symposium, Louann Mlekodaj, Eriko Yamato, Patrick DeRoy and other members of the EMC YP committee organized a Jeopardy game for the Young Professionals Group. As fitting the format of the Jeopardy show at an EMC event, answer categories covered, of course, EMC, SI and PI topics. Read on to test yourself!

This paper details a methodology of using multiple Huygens Boxes on the coupling path to predict RFI/desense at early design stage in mobile devices—all with an aim to minimize the RFI.

Coilcraft’s new Cx Family of surface-mount common mode chokes includes 16 sizes/configurations for a broad range of power line circuits. They suppress high frequency common mode noise up to 100 MHz and offer greater than 40 dB common mode attenuation, making them ideal for use in consumer electronics and industrial applications.

This detailed analysis offers a comparison of various calibration methods for pulse generators according to IEC/EN 55016-1-1 (CISPR 16-1-1), where the spectrum amplitude is measured using different methods and then the results are compared and the measurement uncertainty is determined.

Covering a surface area of 2.3mm x 1.2mm and with a 2mm height, Harwin reports that its S0911-46R shield can clip is the smallest surface mount EMI/RFI shield clip currently available on the market.

At EMV in Stuttgart, Rohde & Schwarz will demonstrate highlights such as the new R&S ELEKTRA EMC test software for automated certification and precompliance tests and R&S AdVISE for automated visual checks. Brand new are the test solutions for spurious emission measurements for 5G components.
