This engineering study investigates resonance behavior in diabolo metal bar optical antennas using FDTD numerical simulations and a dipole oscillator model. It reports that narrowing the antenna waist increases optical absorption and near-field enhancement at resonance and produces a red-shift in resonant…

This study measured satellite structures of second- and third-harmonic spectra reflected from solid targets during femtosecond laser–plasma interactions using an optical multi-channel spectrometer. Red-shifted satellite structures of 2ω0 and 3ω0 were observed, and at ~10^18 W/cm^2 the inferred spontaneous magnetic…
