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 ...

Technical University of Denmark's Anechoic Chamber - RF Cafe Cool Pic

Popular Science magazine ran a short feature titled "Outer Space, Indoors," in the January 2013 edition. The main photo is a shot of the inside of the RF anechoic chamber at the Technical University of Denmark (DTU). Its thousands of RF absorbing pyramids are painted a dark, electric blue with black tips, which makes for a very stunningly artistic image. Narcotics-inspired sculptors of sculptures could scarcely improve on the visual impact of this imminently and supremely functional structure. Interestingly, I could not find a single picture of the anechoic chamber on the DTU website other than a small section of it from before the new paint job. According to my search for the original, the one in PopSci appears to have originated on the website of photographer Alastair Philip Wiper, where many high resolution views of the anechoic chamber's inside are posted. A steel Faraday cage encloses the chamber, but I could not find any photos of it. A picture of the power, data, and RF cabling interface(s) would have been interesting to see.

Be sure to look at the bottom of Alastair Philip Wiper's page for some rather cool other photo collections.
