This paper presents the complex index of refraction and the complex permittivity of a magnetic ceramic material made of copper (Cu), cobalt (Co) and iron oxides. The index of refraction and the extinction coefficient of the CuCo-ferrite exhibit an almost frequency independent behavior and were averaged to n=3.62±0.05 and k=0.06±0.02. The corresponding complex permittivity was e’=13.12±0.35 for the real part and e”=0.46±0.15 for the imaginary part. The absorption coefficient and the transmittance of the CuCo-ferrite were also determined. The absorption coefficient exhibits a dip at ~0.35 THz, which corresponds to a peak in transmittance at this particular frequency. The impact of the observations on the potential realization of novel THz electronic devices is discussed. |
