Finite-difference frequency-domain study of subwavelength lensing in left-handed materials
X. Wang, Stephen K. Gray, George C. Schatz
We show that the finite-difference frequency-domain method is well-suited to study subwavelength lensing effects in left-handed materials (LHM's) and related problems. The method i…

Controlled spatiotemporal excitation of metal nanoparticles with femtosecond pulses
Tae-Woo Lee, Stephen K. Gray
We discuss finite-difference time-domain simulations of femtosecond pulses interacting with silver nanowires and nanoparticles. We show how localized hot spots near the metal surfa…

Surface plasmons at single nanoholes in Au-films
L. Yin, V. K. Vlasko-Vlasov, A. Rydh +7
The generation of surface plasmon polaritons (SPP's) at isolated nanoholes in 100 nm thick Au films is studied using near-field scanning optical microscopy (NSOM). Finite-differenc…
