Stealth technology is a type of military technology that helps aircraft, ships, and other vehicles avoid detection by radar and other sensors. Stealth technology exploits stealthy shapes and materials to minimize reflections from radar signals. Aircraft using stealth technology are able to fly undetected into enemy airspace and launch surprise attacks on ground targets.
Some of the emerging trends in Stealth Technology include the use of 3D printing to create complex shapes, the use of metamaterials to create negative refractive index materials, and the use of photonic crystals to create materials that can bend and redirect light.
