Microwave absorbing properties and electric field distribution of conductor-dielectric compound

摘要：

Complex permittivity of the conductor-dielectric compound was calculated based on the effective medium theory.Four main results are as follows: Microwave absorbing peak shows a blue shift with the increase of conductivity of the inclusion;Increasing the permittivity of the dielectric embedding matrix,significant amplification of the effective permittivity is observed;For fixed surface fraction,effective complex permittivity is independent with the granularity of the inclusion;Local electric field enhancement effect is the main reason that powder metal can be heated by microwave.
