Numerical ray-refraction caustics cast across submerged bathymetric terraces. Airy fold and cusp singularities emerge where the Jacobian determinant of the wave displacement gradient vanishes, modulated by periodic swell.
阶梯下沉到液态介质深处，折射光带在灰层表面交叠。When the swell steepens, adjacent ray paths fold over one another, drifting across the submerged contours like bright salt deposits. 底部的台地不渗漏水，只汇聚焦散线的几何奇点。
Projected ray paths through a bi-chromatic surface wave down to non-planar stepped bathymetry. Calculated caustic intensity via inverse root of the displacement Jacobian $|\det(J)|^{-1/2}$. The fold lines and $A_3$ cusps form crisp caustic ribs along terrace edges, but normal vector discontinuities across step boundaries produced spurious focal points; resolved by smoothing the depth gradient before ray intersection.
