Classification table of common MAMs

Types of MAMs	Typical materials	Loss mechanisms
Dielectric loss material	Carbon materials, non-magnetic metal powder, polymer, non-magnetic metal oxides, non-oxygen ceramics, etc.	Electrical conductivity loss, polarization relaxation loss (dipoles relaxation polarization and interfacial polarization)
Magnetic loss material	Magnetic metals and compounds, ferrite, carbonyl iron, etc.	Hysteresis loss, eddy current loss and residual loss
Multiple loss material	Combination of the above	Multiple loss
