Polarization and transmission of microwaves in the magnetic suspension in the applied magnetic field

► Suspensions containing iron particles dispersed in cedarwood oil were produced. ► Passage of microwaves throughproduced suspensions placed in a magnetic field was investigated. ► Conducted investigations show that microwaves were damped and polarized in these suspensions. ► Observed results depended on parameters characterizing field, particles, and liquid carrier. ► Results can be explained by microwave interaction with ordered structure of particles in the field.
