Stealth technology primarily relies on specific geometric designs that reflect radar waves away from their source, allowing aircraft like the F-117 and B-2 bombers to evade detection. The F-117 employs angled surfaces to achieve this, while the B-2 uses a technique known as continuous curvature, which enhances radar evasion. Stealth does not render aircraft invisible but reduces their radar signature, enabling them to navigate through gaps in radar coverage created by overlapping radar defenses. Research is also ongoing into stealth suits designed to make soldiers less detectable, utilizing pinhole cameras to project images from the environment. However, these prototypes have limitations, such as low resolution and heat signature issues. The Philadelphia Experiment, a controversial topic, suggests the use of magnetic fields to bend light around objects, but remains largely regarded as a conspiracy theory.
