Problem: Compliance Labs Inc. of Middlefield, Ohio requested Wright Technology Network (WTN) assistance with radio frequency emissions. Compliance Labs was installing an anechoic chamber to test electronic equipment for spurious radio frequency emissions. The chamber is designed to satisfy European requirements and it was exhibiting problems at certain frequencies.
Solution: Compliance Lab's solution was to install magnetic ferrite radar absorbing materials which were effective, but fairly costly. The company had read of a new magnetic absorber made of chiral composites. Chiral composites are composed of molecules of a certain structural configuration having the property that none of the molecules are symmetrical with their mirror images. It is hypothesized that such molecules will result in materials which are more absorbing and less expensive than current ferrite absorbers. The company requested WTN comments and recommendations.
