Recent advances in laser technology and plasmonics highlight the key role of resonating
particles in boosting wave energy absorption and fusion initiation. We used numerical
modeling to study the interaction between laser radiation and gold nanoparticles with
different orientations. We investigated the response of gold-doped materials to intense
infrared radiation, focusing on electron ejection dynamics and near-field enhancement.
Optimal orientation results in an order of magnitude increase in the electric field.
Furthermore, we introduce a shape that is less sensitive to orientation, giving better
near-field enhancement than the original resonant nanoparticle at medium intensity
field. These findings are crucial for future fusion research, particularly in the
context of high-energy short laser ignition pulses within the NAPLIFE project. This
article is a short overview of the presentation with the same title on Particles and
Plasmas Symposium 2024 held in Budapest.
