N2  - We propose and demonstrate a scattering-type near-field probe, designed to increase the sensitivity of high-resolution scattering probe microscopy at terahertz (THz) frequencies. For efficient scattering of THz radiation, the probe, fabricated from indium, is designed to resonate like a dipole antenna. Efficient excitation is achieved by integrating the probe with a radially-polarized THz source. Using time-domain spectroscopy (TDS), we observe resonant enhancement of the scattered fields, and using aperture-type near-field microscopy, we see high field confinement at the scattering probe apex.
