Complex permittivity and permeability of barium and strontium ferrite powders in X, KU, and K-band frequency ranges
This paper presents accurate results for the complex permittivity, ε=ε′−jε″ and permeability, μ=μ′−jμ″ of barium ferrite powder (BaFe12O19) and strontium ferrite powder (SrFe12O19), in the frequency range from 8.0to26.5GHz. The complex permittivity and permeability are determined via the waveguide t...

| Zusammenfassung: | This paper presents accurate results for the complex permittivity, ε=ε′−jε″ and permeability, μ=μ′−jμ″ of barium ferrite powder (BaFe12O19) and strontium ferrite powder (SrFe12O19), in the frequency range from 8.0to26.5GHz. The complex permittivity and permeability are determined via the waveguide transmission/reflection (TR) technique and the waveguide cavity resonator (CR) technique at 25°C and relative humidity |
