Abstract :
Summary form only given. We report on the experimental study of the probe shape dependency on terahertz near-field enhancement near the tip of a metallic probe in the apertureless terahertz scanning near-field microscope. It was established that terahertz near-field signal is strongly controlled by the cone shape of the probe and varies by an order of magnitude depending on the shape of the probe.
