Scientists Develop Lightweight, Flexible Metamaterial using Graphene and Aluminum Oxide A new type of metamaterial promises to be super-light and incredibly strong.
All Ferrite Beads Are Not Created Equal – Understanding the Importance of Ferrite Bead Material Behavior A ferrite bead is a passive device that removes noise energy from a circuit in the form of heat. The bead creates impedance over a broad frequency range that eliminates all or part of the undesired noise energy over that frequency range.
