Chinese researchers achieve 3D underwater acoustic carpet cloak first with ‘Black Panther’-like features

Recently, a research team led by Prof. YANG Jun from the Institute of Acoustics (IOA) of the Chinese Academy of Sciences designed and fabricated a 3D underwater acoustic carpet cloak (UACC) using transformation acoustics. Like a shield, the carpet cloak is a material shell that can reflect waves as if the waves were reflecting off a planar surface. Hence, the cloaked target becomes undetectable to underwater detection instruments like sonar.

Russia plans INVISIBLE ‘STEALTH’ TANKS as scientists storm towards military breakthrough

This is reminiscent on British and American technology that have been under development for over a decade now, with the Chinese also following suit.

RUSSIA is close to developing “invisible” tanks due to a huge scientific breakthrough.

Scientists in Moscow have created a new material which makes war vehicles invisible to radar by manipulating electromagnetic waves.

Researchers at the city’s National University of Science and Technology have created a material which can block, absorb or bend waves, making the tanks essentially invisible.
