Abstract

We describe the angular dependence of near-field signals generated in super-resolution near-field structure (Super- RENS) disks. The carrier-to-noise ratio (CNR) of transmitted signals using different numerical aperture's (NA's) lenses, were mostly the same values, experimentally. While on computer simulation by finite-difference time-domain (FDTD) method, it was found that most scattered signals were trapped around the optical axis.
