EM Coating for Low Frequency Magnetic Shielding
Integran Technologies’ Nanovate EM coating for low frequency magnetic shielding achieves similar performance to specialty discrete magnetic shielding foils, but uses a process that allows a nanocrystalline metal to be applied directly to metal, polymer and composite substrates. The process flexibility enables applications where part size or complexity makes the use of formed … [Read more...]
Unshielded Copper Cable Fails Tests
A U.K.-based copper and fiber cabling system manufacturer announced what it said were surprising results of interference testing of high-performance cabling and 10GBASE-T interface cards. The tests performed indicated that unshielded twisted-pair Category 6 cable was “seriously susceptible to electromagnetic interference and alien crosstalk,” according to a company statement. … [Read more...]
Approved Idaho Defense and Military Projects Include EMP Study
About $26 million worth of Idaho defense and weapons-related projects are closer to being funded by the federal government after winning approval from the U.S. Senate Appropriations Committee. The funding includes $1 million for Idaho National Laboratory in Idaho Falls to study electric grid reliability/assurance. This project would develop the capability to perform … [Read more...]
