Abstract

An optical black hole is studied using a parallel radially dependent finite-difference time-domain (FDTD) simulation technique. The device requires non-dispersive metamaterial structures and is capable of broadband operation, based on transformation optics. Excellent absorption is demonstrated for different angles of wave incidence and illumination excitation types. In addition, a practical device, which is made to be matched to free space, is proposed, and the relevant physics is explored. Finally, peculiar phase distributions of the electromagnetic waves are observed inside the radially dependent permittivity material of the devices.
