| Research Abstract |
We have developed an apertureless SNOM (a-SNOM), and have studied the polarization properties of the a-SNOM. As a result, we have succeeded to obtain a spatial resolution of approximately 10 nm. In addition, we have also succeeded to resolve a SNOM signal and a background signal. FDTD simulation explained our experimental results well, and consequently, we understood electric fields underneath apertureless probes. Furthermore, we developed a system for time-resolved SNOM measurement.
