Abstract

It is shown how a recently proposed method of cloaking is effective over a broad range of frequencies. The method is based on three or more active devices. The devices, while not radiating significantly, create a “quiet zone” between the devices where the wave amplitude is small. Objects placed within this region are virtually invisible. The cloaking is demonstrated by simulations with a broadband incident pulse.

Fig. 1.

Wave field at the central frequency ω 0 when the cloaking devices are (a) inactive and (b) active. Only the real part of the fields is displayed, with a linear color scale going from -1 (dark blue) to 1 (dark red). All fields have been rescaled by |ui (x,ω)| to remove the geometric spreading of the point source.

Cloak performance in terms of the cloaked region radius α, as measured by (a) ‖ui +ud ‖/‖ui ‖ with the L 2 norm on |x|=α and (b) ‖ud ‖/‖ui ‖ with the L 2 norm on |x|=γ. Dashed, solid and dash-dotted lines correspond toω/(2π)=1.2GHz, 2.4GHz and 3.6G

Estimate of the radius of circular cloaking devices relative to the radius of the cloaked region α. Dashed, solid and dash-dotted lines correspond to ω/(2π)=1.2GHz, 2.4GHz and 3.6GHz, respectively. The device radius is estimated as the largest of the distances from a device point x m to the level-set |ud |=100max|x|=α |ui (x,ω)|. If the devices were perfect circles, any device radius below the dotted line (at cos(π/6)δ/α=5√3/2) would indicate that the devices do not touch, i.e. they are three disjoint devices.
