Metasurfaces have emerged as fascinating planar optical components and devices, and, in particular, active metasurfaces confer more multifunctional expansions. However, the metasurface research has mainly focused on operating the light in free space, which hardly satisfies the system‐level compactness and miniaturization. The potential of the metasurface for guided wave modulation remains to be further...
Aims
Fibroadipose vascular anomaly (FAVA) is a complex vascular malformation that is likely to be under‐recognised. In this study we aimed to report the pathological features and somatic PIK3CA mutations associated with the most common clinicopathological features.
Methods and results
Cases were identified by reviewing the lesions resected from patients with FAVA registered at our Haemangioma Surgery...
