K. Hirota et al., Design of a near-field probe for optical recording using a 3-dimensional finite difference time domain method, JPN J A P 1, 39(2B), 2000, pp. 973-975
Tapered dielectric near-field probes are designed for optical recording by
means of a 3-Dimensional finite difference time domain (FDTD) method. Probe
fabrication is attempted with a double-exposure holographic technique.
