Near-Field Optical Flying Head with A Triangular Aperture

Heat assisted magnetic recording head needs near-field element as a micro heat generator and light guide structure. We have proposed a triangular aperture as a near-filed element. Computer simulation using finite difference time domain (FDTD) method shows that the triangular aperture has a near-fiel...
