Radar Absorbent Materials (RAM) are specialized substances designed to reduce the reflection of radar waves. They work by absorbing electromagnetic energy, which helps to minimize the visibility of objects, such as military aircraft or ships, on radar screens. This property is crucial for stealth technology, allowing vehicles to evade detection. These materials can be made from various compounds, including polymers and metals, often combined with specific additives to enhance their effectiveness. The design and application of RAM are essential in modern defense systems, contributing to the development of advanced stealth technology used by many military forces worldwide.
