Description
Shuo Sun and seven colleagues build a microwave absorbing sponge from wood carbon laced with silica aerogel. Wood's aligned cells survive charring, giving the sponge a built in direction sense that earlier biomass absorbers rarely exploited. The team measured how the material handles microwaves along the grain, across the rays, and around the trunk. Each direction behaved quite differently.
One direction swallowed microwaves across a very wide band at under five millimeters thick, covering two whole radar bands. Another reached the deepest single absorption reading. The sponge also insulates heat well and springs back under squashing, unevenly by direction. Sun and the team present wood's natural grain as a design lever for light stealth materials that also keep heat in or out.
