FORMATION OF PLASMONIC NANOJETS BY SILVER NANO-STRIP

In this work the "central" surface plasmon-polariton was obtained by using frequency dependent difference time-domain method for the TM- polarized light at 532 nm, which was propagating through the silver nano-strip, placed on silica glass in an aqueous medium. The height and width of nano- strip was equal to 20 nm and 215 nm respectively. The intensity of surface plasmon-polariton was 4 times higher the intensity of the incident radiation. The full width at half maximum of the nanojet was 138 nm.
