摘要：
A terahertz near-field imaging probe and a terahertz near-field imaging system. The terahertz near-field imaging probe comprises a Sommerfeld line waveguide end (110) for coupling and transmitting a terahertz wave with radial polarisation, and a probe tip (120) integrally formed with the Sommerfeld line waveguide end (110). The probe tip (120) is used for focusing the terahertz wave at a near field of the probe tip (120) so that the terahertz wave carries information about a sample to be detected and reflects the terahertz wave carrying the information about the sample to be detected to the Sommerfeld line waveguide end (110). The terahertz wave transmitted in the Sommerfeld line waveguide end (110) is referred to as a Sommerfeld wave, has an ultra-large bandwidth (0.1 THz - 5 THz), and has the properties of ultra-low loss and ultra-low chromatic dispersion within the range of the large bandwidth. The probe tip (120) can focus the terahertz wave (the Sommerfeld wave) such that same is extremely small by focus
