Evanescent field localized at the interface with the total internal reflection. Although the amplitude distribution is well known long time and theoretically derived easily, it is difficult to detect experimentally. Because the probe inserted in the region of evanescent field disturbs the distribution. This time, we proposed a technique to detect the amplitude without disturbing. The principle of the technique is verified with FDTD simulation result.
