CLOAKING SYSTEM WITH WAVEGUIDES

摘要

Described herein are technologies related to passive or active cloaking devices. More particularly, the passive or active cloaking devices utilize input/output grating couplers and waveguides to create an impression of invisibility on an object that is covered by the passive or active cloaking devices.
