This type of RADAR Absorbent Material (RAM) reduces the RADAR return by attacking the magnetic portion of the Electromagnetic (EM) wave. What is it called?

Ablative RADAR Absorbent Material (RAM) is designed to reduce RADAR returns specifically by targeting the magnetic portion of the electromagnetic (EM) wave. This type of material works by absorbing the energy of the radar waves, effectively diminishing the strength of the reflected signal that would otherwise return to the radar system.

The process involves a physical response to the electromagnetic fields, where the material might undergo changes or degradation as it interacts with the radar waves, thereby transforming the electromagnetic energy into a form that does not return to the source. This makes ablative RAM particularly effective in stealth applications, where minimizing radar signatures is crucial for evading detection.

In contrast to other forms of RAM that might operate based on different principles—such as non-resonant materials that rely on broader frequency applications without specific magnetic targeting—ablative RAM provides a significant advantage by focusing on the absorption mechanism that directly affects the return signal at particular frequencies where radar systems operate.
