- Particulate powder that can be used in flux field directional or absorber material constructions
- High permeability and low loss magnetic material at frequencies below 20 MHz
- High magnetic loss above 50 MHz
- Sub-skin depth NiFe layers for effective penetration of RF fields at high frequencies
3M™ Flux Field Directional Materials (FFDM) Particle EM05EC is a permeable multi-layered NiFe/insulator particulate material consisting of multiple sub-skin-depth magnetic layers alternated with dielectric spacer layers.
