Query: A New Paradigm in Chaotic Ray Scattering   We introduce a new paradigm of 2D (electromagnetic) ray-chaos, featuring both
guided and scattered rays in a dielectric layer with exponentially tapered
refraction index backed by an undulated conductive surface, and illustrate its
relevant features. Numerical simulations of the corresponding full-wave
solution indicate that the system complies with Berry's conjecture in the
asymptotic short wavelength limit.
