Figure 13. — (a) Near-field distribution of the absolute value of the electromagnetic wave magnetic field |H_w| in the plasmonic crystal (shown in the inset above) normalised to the magnetic field of the incident light |H_wi|; (b) Distribution of the effective magnetic field H_eff generated in the plasmonic crystal by the laser pulse. Three periods of the structure are shown. A laser pulse with a peak intensity of 500 W/μm² is p-polarised and is obliquely incident at 10°. Period d = 400 nm, slit width is 120 nm, and nickel film thickness is 100 nm. Reproduced from [133] with permission by American Physical Society, Copyright 2012.
