Webb14 aug. 2024 · We present the temporal evolution of the terahertz (THz) field leading to the excitation of plasmonic resonances in carbon microfibers. The field evolution is mapped in space and time for the 3/2 wavelength resonance using a subwavelength aperture THz near-field probe with an embedded THz photoconductive detector. Webbfar-zone electric fields, we used the near field-to-far field transformation technique using the virtual surface enclosing the entire emitting structure. The THz generation system is simulated through in-house 3D FDTD-based codes. The computational volume is 50 × 20 × 50 µm3 with a five-layer uniaxial perfectly matched layer.
