Abstract

Using a photomixer-equipped probe-tip and a fiber-coupled two-color diode laser, optoelectronic coherent terahertz near-field measurements are reported in the frequency-domain for the first time. The system is successfully applied to spatial and spectral investigations of resonant metamaterial structures.
