- U.S. Army scientists at the CCDC Army Research Laboratory
(ARL) have developed a first-of-its kind antenna that could change how
ground vehicles and airborne systems communicate, transmit and receive
radio frequency signals. The Army used a manufacturing process based on a
special class of engineered materials known as metaferrites
to make an ultra-thin wideband antenna. The antenna conforms to curved
surfaces, making it ideal to integrate into unmanned aircraft systems,
rotary wing aircrafts and ground vehicles. more
- Of ever-increasing concern for operating a tactical communications
network is the possibility that a sophisticated adversary may detect
friendly transmissions. Army researchers developed an analysis framework
that enables the rigorous study of the detectability of ultraviolet
communication systems... In particular,
ultraviolet communication has unique propagation characteristics that
not only allow for a novel non-line-of-sight optical link, but also
imply that the transmissions may be harder for an adversary to detect. more
