Wave propagation through random continuous media is an important fundamental problem with applications ranging from remote sensing to quantum communication. We refine the methods for accurate numerical simulation and table-top experiments of such media by introducing novel hybrid phase screens. Within this framework, we investigate the effects of disorder on structured light and show how instantaneous spatial singular modes of light offer improved high-fidelity signal transmission in dynamically evolving media compared to standard encoding bases. We show that power-law spectra such as the atmospheric Kolmogorov spectrum induce a subdiffusive algebraic decay of transmitted power as a function of time.
