    "abstract": "We discuss finite-difference time-domain simulations of femtosecond pulses\ninteracting with silver nanowires and nanoparticles. We show how localized hot\nspots near the metal surfaces can be generated and controlled in a\nspatiotemporal manner. The control is made possible by chirping the pulses such\nthat the effective frequency passes through surface plasmon resonances\nassociated with different spatial regions of the nanostructure over the course\nof time. The response of such nanostructures to chirped pulses could provide a\nnovel means of encoding or decoding optical signals.",
