摘要：

Gyrotropic hexaferrite materials are believed to be very promising candidates for operation in non-reciprocal devices at terahertz frequencies. We present full permittivity and permeability tensor characterization of different hexaferrite crystalline and ceramic samples in a wide band (0.075 - 5 THz) using both an original magneto-optical Time-Domain-Spectrometry setup and a magneto-quasi-optical setup using Vector-Network-Analyzer-controlled frequency multipliers. The obtained gyrotropic THz spectra allow validation of a novel concept for a compact THz isolator based on a one-way reflecting surface, that will also be presented.
