摘要
Methods of detecting a perfect invisible cloak are analyzed. A classical frequency-domain method of detection is proposed. It is based on the detection of the difference between the nonlinear responses of the materials of the cloak and the background. The cloak treated here is perfect working within any frequency. The method for detecting the cloak in the frequency domain is demonstrated numerically for an example.
