[Yongpeng Sun-Tastaufen]

Radio absorbing materials is like solar panel. Whereas solar panel absorbs solar electromagnetic radiation AKA visible light, radio absorbing material is supposed to absorb radio electromagnetic radiation. Solar panel can absorb up to 15 percent or so. RAM probably can absorb up to 5 percent or so because it's much thinner than solar panel.

F-22 entered service in 2005.

Su-35 entered service in 2014.
