We highlight their genericity and analyze the connection of the refracting interface topography and curvature landscape with the caustics' (and their images') topology.encircular cross-sectionscombined watergenericitymolecular physicsoptics620535Optical caustics of multiple objects in water: Two vertical rods and normally incident lightjournal article
