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…
