WebApr 5, 2024 · Photonic crystals are optical structures whose ability to refract light changes periodically (that is to say, over time). In lab settings, the electromagnetic properties of metamaterials can be... WebWe investigate analytically and computationally the dynamics of 2D needle crystal growth from the melt in a narrow channel. Our analytical theory predicts that, in the low supersaturation limit, the growth velocity V decreases in time t as a power law V ∼ t − 2 / 3 , which we validate by phase-field and dendritic-needle-network simulations.
