RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

My Hobby Website:
When this Engineer's Survival Kit appeared in my RF Cafe Twitter feed, I though it was a gag item, but it turns out to be a very useful experimenter's resource for mitigating EMI/RFI issues, provided at no cost by ARC Technologies - at least for now. It comes with a variety of RF absorber materials in different thicknesses and form factors that address frequencies from 50 MHz through 110 GHz.
The sheets of foam-based material are good, but what caught my attention - and is the reason I bothered to post this promo - is the heat-shrink tubing product. I have never seen EMI/RFI shielding in that format before. It should be very effective in preventing interference leakage into an assembly via a power and/or signal cable connector port or bulkhead feedthrough. It won't be much help if the interference is already on the wire before it hits the shielding, but it will complete the integrity of the Faraday shield action of a metal enclosure.
Per the ARC Technologies YouTube page:
"ARC Technologies Inc. offers a complete range of custom and standard absorber products that provide solutions to the diverse RF and EMI problems facing today's military, aerospace, and commercial electronics design engineers. We are dedicated to understanding our customer’s needs, delivering quality products on-time, and engineering innovative solutions. Whether a customer is facing interference problems at 50 MHz or 110 GHz, nearfield or farfield, narrowband or broadband, we have an absorber product or will develop an application-specific product to meet its requirements.
