Concentricoconcentrica

Concentricoconcentrica is a coined term used to describe a pattern or system in which circular elements are organized in concentric layers at multiple scales, creating nested rings with a shared center. The concept emphasizes dual concentric organization: a primary arrangement of circles or cylinders that are concentric, and a secondary, concentric variation within or across those layers. It is typically employed in discussions of design, geometry, or pattern formation to signal a strongly radial, self-similar structure.

Etymology and usage notes: the word blends con-centered roots commonly associated with concentric shapes. It is not a standard term in formal mathematics or established design lexicons, and its precise definition can vary by discipline. When used, it usually reflects a deliberate, multi-tiered concentricity rather than a single, flat ring pattern.

Formal characteristics: the hallmark is radial symmetry about a central point, with circular or cylindrical elements arranged in rings. In concentricoconcentrica systems, there is often a nested or hierarchical layering where each ring itself exhibits a concentric organization, possibly with gradients of a property such as thickness, density, color, or material composition. Spacing between rings may be uniform or purposely varied to enhance the nested effect.

Applications: the concept appears in fields such as visual design, optics (annular filters and multi-ring lenses), acoustics (ring-array configurations), geology (banded cores), and urban planning (ring-road networks with inner zoning). In nature, patterns like tree rings or certain mollusk shells can resemble concentricoconcentrica arrangements.
