Low-Field Non-Reciprocal Terahertz Devices Indium antimonide (InSb) rod arrays enable robust unidirectional propagation at terahertz frequencies under low magnetic fields (0.1 T). By exploiting the Voigt effect and dispersive scaling, this work realizes magnetic-field-controlled non-reciprocal devices that exhibit topological immunity to defects and sharp bends.
