Description

Recently Nanoplasmonic Laser Induced Fusion Experiments were proposed, as an improvement in achieving laser driven fusion [1]. This combines recent discoveries in heavy-ion collisions and optics. The existence of detonations with time-like normal on space-time hyper-surfaces combined with absorption adjustment using nanoantennas allows the possibility of heating the target in an opposing laser beam setup [2]. For tracking the time evolution of non-equilibrium plasma interacting with strong laser fields, kinetic modeling is most proper way. However, to describe the absorption effects of gold nanoantennas inside a medium, one requires different approaches. Here we will present a particle-in-cell model of resonant nanoantennas using the capabilities of the EPOCH multi-component PIC code[3].
