In pursuit of efficient high-order harmonic conversion in semiconductor devices, modeling insights into the complex interplay among ultrafast microscopic electron–hole dynamics, nonlinear pulse propagation, and field confinement nanostructured materials are urgently needed. Here, a self-consistent approach coupling Bloch Maxwell equations is applied to compute transmission reflection spectra for finite slab sub-wavelength nanoparticle geometries. An increase generated high harmonics by several orders magnitude predicted gallium arsenide nanoparticles with size maximizing magnetic dipole resonance.
