Abstract
Electro-mechanical transducers are used to actively cloak a targeted object in a way that absorbs incoming waves without reflection, sends them out the opposite side of the target and returns the wave without leaving a shadow behind the target. The present invention pertains to an improvement in the cloaking of an object without requiring the use of special materials for the object itself and allows the use of SONAR and other possible transducer systems that would be covered and rendered ineffective with passive cloaking materials.
