The free space electromagnetic wave at infrared or THz frequencies is focused in this extremely small area compared to the wavelength. In many cases, the probe is a classical AFM-tip which was not designed and fabricated for this purpose. We present here an original approach in order to optimize the interaction between the impinging electromagnetic wave and the antenna-like probe. As a proof of concept we have modified with FIB (Focused Ion Beam) technique a commercial AFM-tip. The results in terms of resolution are very encouraging.Show less >
