Radar absorbing materials or RAMs have emerged as one of the most important components in the modern era of stealth and electromagnetic wave management. These materials are designed to absorb incident radar waves, thereby reducing the radar cross-section of objects and making them less visible to radar detection systems. Over the years, RAMs have evolved from being niche defense technologies to materials with applications across aerospace, telecommunications, automotive, and even healthcare industries. The increasing use of radar technologies, rising concerns about electromagnetic interference, and continuous defense modernization programs are propelling the demand for these specialized materials across the globe.

According to Persistence Market Research the global radar absorbing materials market size is likely to be valued at US$0.8 Bn in 2025 and expected to reach US$1.0 Bn by 2032, registering a robust CAGR of 3.8% during the forecast period from 2025 to 2032. This growth is being driven by a combination of defense investments, advances in material science, and broader adoption of radar technologies across multiple industries.
