Radar-Absorbing Materials (RAM) are specially designed substances that reduce the reflection of radar waves. These materials are used in various applications, including military stealth technology, to make aircraft and ships less detectable by radar systems. By absorbing radar signals instead of reflecting them, RAM helps to enhance the effectiveness of stealth operations. Commonly made from composites, metals, or polymers, RAM can be applied as coatings or incorporated into the structure of an object. The effectiveness of these materials depends on their composition and thickness, which can be tailored to specific frequencies of radar waves, making them crucial for modern defense strategies involving stealth technology and electronic warfare.
