THz near-field inspection of metamaterials for bio-sensing applications featuring single-resonator read-out capability

We present contact-free Terahertz (THz) near-field measurements with microscopic resolution at meta-surfaces built from bow-tie resonators with broad spectral response and nanoslits featuring strongly localized THz fields. We will demonstrate single resonator read-out on wafer-scale measurement areas and the application as functionalized bio-sensor.
