Fig. 3: Numerical simulations of optical Schwarzschild black holes.
From: Optical analogues to the equatorial Kerr–Newman black hole
Finite-difference frequency-domain simulations of light incident on an optical Schwarzschild black hole with impact parameters \(\hat{b}_\infty =\) a 2, b 3, c 4, and d 5. True geodesics are plotted as thick lines. Poynting vectors (white arrows) are scaled by ∝1/R. Edge radii and Schwarzschild radii (RS) are solid circles. Each interior annulus's edge is marked. Color scales for the normalized electric field amplitude \(\left|E\right|/\!\max \left|E\right|\) are the same for each subplot.
