The United States is also developing a nanotech coating that can absorb 99 % of radar's electromagnetic waves. An airplane with such a coating would be able to avoid detection by radar. When nanotech gets really hot, scientists will be able to create new materials by arranging particles and atoms at will.
又例如美國利用奈米科技來研製一種「超碳黑隱身塗料」，這種塗料對雷達電磁波的吸收率高達百分之九十九，塗在戰鬥機上，可以躲避對方雷達的偵測，成為名符其實的「隱形」飛機。
