🫥 Invisibility Cloak: Ray Cross-Section (2D)

Interactive 2D cross-section of a transformation-optics invisibility cloak: a beam of rays bends around a hidden object inside the shell and leaves undisturbed, compared live with a bare opaque object and a Snell's-law glass sphere, with a screen intensity profile and a detectability score.
