Abstract

In this work the "central" surface plasmon-polariton was obtained by using frequency dependent finite difference timedomain method for the TM-polarized light at 532 nm, which was propagating through the silver nano-strip, placed 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 four times higher the intensity of the incident radiation. The full width at half maximum of the nanojet was 138 nm. The "central" surface plasmon-polariton was obtained by using frequency dependent finite difference time-domain method for the radial-polarized light at 532 nm, which was propagating through the silver nanocircle, placed on a silica glass in an aqueous medium. The height and width of nano-strip was also equal to 20 nm and 215 nm respectively. The intensity of surface plasmon-polariton was four times higher the intensity of the incident radiation. The full width at half maximum of the nanojet was 158 nm. The results can be used to design devices that allow capturing and moving the particles in water or other biofluidics.
