  • Exploited the Voigt effect for magnetic-field control of propagation.
  • Investigated the impact of dispersive scaling on terahertz frequencies.
  • Achieved robust unidirectional terahertz propagation at low magnetic fields (0.1 T).
  • Demonstrated topological immunity to defects and sharp bends in the device.

Abstract

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.
