A thermally conductive electromagnetically absorbing material includes a plurality of particles dispersed in a binder. The plurality of particles can have a particle size distribution having at least three peaks, where at least a majority of particles within a half width at half maximum of one, but not the other ones, of the at least three peaks are at least partially coated with an electromagnetically absorbing coating. The plurality of particles can include pluralities of first and second particles where a total number of the first particles is at most 1% of a total number of the first and second particles and where the first particles are more electromagnetically absorbing than the second particles. Films, molded articles and systems including the thermally conductive electromagnetically absorbing material are described.

The disclosure generally relates to shielded transmission lines, electrical systems including the shielded transmission lines, cables using shielded transmission lines, and electrical connectors using shielded transmission lines. In particular, the present disclosure provides transmission lines that include floating shields capable of isolating interference between conductors that can result in reduced crosstalk.

Floating connector shield

A wireless connector includes a plurality of printed circuit boards (PCBs) () disposed within a housing of the electronic system. Each PCB comprises a plurality of transceivers () configured to wirelessly transmit and receive modulated carrier signals (). Each transceiver in the system is configured to receive signals transmitted by every other transceiver in the system.
