The multifrequency scheme for optical lattices [1] offers a stable and highly tunable approach for generating complex lattice geometries. Here I present some results of my master's thesis, where I performed numerical simulations of the eigenspectrum and Kapitza-Dirac dynamics for a 5-fold symmetric quasiperiodic optical lattice, revealing localization properties and spectral features. Additional Kapitza-Dirac simulations and preliminary absorption images for a non-separable 3D multifrequency lattice are presented as a first step toward exploring these lattice configurations.
