Abstract
Cloaking of macroscopic objects of any specific design is of paramount interest and still remains a challenge, despite of successful demonstration of certain test objects, especially using optical frequencies. This presentation illustrates a relatively new concept of using plasmonics for optical cloaking, especially used for critical assets. Metamaterials have demonstrated flexibility in manipulating electromagnetic waves and producing new functionalities, including the invisibility cloaking based on coordinate transformation. The concept suffers from major limitation, nevertheless has demonstrated a potential use for future applications. The presentation outlines the principles of design of metamaterial implementation for cloaking at the optical frequencies. Optical invisibility is one of the many tools in an ecosystem of innovations to enhance peace and security globally. An outline of some additional tools employing nanomaterials considered in support of smart defense doctrine will be outlined.
