Abstract Symmetry, a core principle of aesthetics, plays crucial role in both physics and mathematics. Recent investigations into high‐symmetry meta‐structures (C m , ≥ 3) have revealed intriguing concepts phenomena optics materials science. However, increasing symmetry introduces challenges tailoring anisotropy, limiting the potential highly symmetric structures for functional wavefront engineering. While nonlinear geometric Berry phase generalized enabled circular polarization control C ( meta‐structures, these approaches are inherently spin‐dependent restricted to states. Here, shape tailoring, including modifications unit cell dimension meta‐structure parameters is presented, effectively enhance anisotropy capabilities meta‐structures. By further incorporating phase, independent arbitrary orthogonal states achieved, validated numerically experimentally. This framework enhances capacity has substantial integrating flexible functions with high‐symmetry‐driven exotic phenomena. Moreover, this approach offers inspiration applications fields such as condensed matter science, i.e., lattice.

Abstract Current membrane oxygenators for extracorporeal life support (ECLS) are facing their limits regarding gas exchange efficiency and long‐term stability. One aspect adding to these limitations is inhomogeneous blood flow distribution inside the oxygenator's structure. Triply periodic minimal surface (TPMS) lattice structures proposed provide increased mass transfer local adaptability introducing heterogeneous properties. However, adaptation of flow, as in ECLS, challenging a hemocompatible must be established. In this study, study proposes novel method smooth, multi‐scale modification TPMS creating tailored suited blood‐gas exchange. It implements into an automatic structure optimization within oxygenator. After manufacturing prototypes, it experimentally evaluate 3D using time‐resolved, contrast enhanced computed tomography comparing optimized reference geometries. The provides significant change distribution, improving homogeneity by up 12%. approach can directly transferred various other applications field heat enhance functionality, e.g., exchangers or contactors.
