Abstract

We show in principle how to cloak a region of space to make its contents classically invisible or transparent to waves. The method uses sensors and active sources near the surface of the region, and could operate over broad bandwidths. A general expression is given for calculating the necessary sources, and explicit, fully causal simulations are shown for scalar waves. Vulnerability to broad-band probing is discussed, and any active scheme should detectable by a quantum probe, regardless of bandwidth.

Simulation results, shown for an equatorial (x-y) plane of the spherical volume to be cloaked, at a time t=+25 in the still figures, for the propagation of a pulse from left to right through the volume. The vertical color bar shows the false color scale. (a) Coordinates, position of cloaked volume (dashed circle), and point P for Fig. 3 results. (b) Movie of original unperturbed pulse (876 KB), focused approximately at the center of the volume, and arriving there approximately at time t=0. (c) Movie of approximate “quasi-cloaking” (930 KB), using surface sources with values derived only from local measurements. Significant distortion of the transmitted pulse is seen. (d) Movie of approximate “true cloaking” (894 KB), with surface source values calculated from the measured wave at current and past times at all the measurement points near the sphere surface; the propagated pulse is then substantially unchanged.
