Abstract :
This paper investigates complex refractive index and wave-impedance of commercial permanent-magnet hexaferrites, which are suitable for use in quasi-optical nonreciprocal devices at millimeter and submillimeter wave frequencies. The measurements are realized by using broadband quasi-optical bench and vector network analyzer in the frequency range 75-630 GHz.
