AB The interaction of ultrashort, high intensity laser pulses with thin foil targets leads to ion accelerationon the target rear surface. To make this ion source useful for applications, it is important to optimizethe transfer of energy from the laser into the accelerated ions. One of the most promising ways toachieve this consists in engineering the target front by introducing periodic nanostructures. In thispaper, the effect of these structures on ion acceleration is studied analytically and with multidimensionalparticle-in-cell simulations.Weassessed the role of the structure shape, size, and theangle of laser incidence for obtaining the efficient energy transfer. Local control of electron trajectoriesis exploited to maximize the energy delivered into the target. Based on our numerical simulations, wepropose a precise range of parameters for fabrication of nanostructured targets, which can increase theenergy of the accelerated ions without requiring a higher laser intensity.
