“…RWs are found to have many different fundamental patterns, such as eye-shaped one, anti-eye-shaped one, and four-petaled one, etc. Scalar ones usually admit eye-shaped one [6,7], while vector ones admit anti-eye-shaped one and four-petaled one [8,9,10,11,12,13,14]. ABs with infinite period tend to be RW, but ABs with finite period admit different pattern with RW (the hump amplification rate is different and the valley values are also distinctive).…”
