Description
Rapid progress in technology of lasers and methods learned from astrophysics and relativistic heavy ion collisions led to new possibilities for fusion [1,2]. When nanoantennas are implanted into the target and resonate with the laser frequency, electrons form bunches within them. The motion of these bunches generates the nanoplasmonic wave. Particle-in-cell simulations are not typically employed to describe these interactions. However, this method allows for the consideration of additional effects beyond those traditionally used [3].
Our recently shown kinetic model with a Hydrogen target indicated that the field of these resonating electrons attracts and accelerates the surrounding protons. Now we will show the behaviour of multiple nanoantennas in array interacting with two-sided irradiation. We will show the effects of various size, orientation and shape of nanoantennas on the proton energies, we will discuss the dynamics of energy absorption under irradiation of short laser infrared pulses at above ~$10^{15}$ W/cm$^2$ intensities. These protons are then energetic enough to achieve nuclear transmutation and fusion reactions. Without resonating nanoantenna there is no such collective proton acceleration.
