Optical cloaking
WebTheories of cloaking discusses various theories based on science and research, for producing an electromagnetic cloaking device.Theories presented employ transformation optics, event cloaking, dipolar scattering cancellation, tunneling light transmittance, sensors and active sources, and acoustic cloaking.. A cloaking device is one where the purpose of … WebDespite much interest in the cloaking, large-size cloaking has not been achieved without some limitations and/or assumptions. To solve this problem, a computational design method is proposed for an optical cloaking display via viewpoint transformation. The method uses two kinds of passive optical elements that transfer a point into a plane ...
