Abstract: A device and method for absorbing electromagnetic waves can include a honeycomb sheet formed by a plurality of interconnected hexagon cells arranged in rows. The hexagon cells are made up of sidewalls, each sidewall formed by two surfaces that converge at a top of the sidewall and diverge from the top to a bottom of the sidewall such that a thickness of the sidewalls increases from top to bottom and an angle forms between the two surfaces at the top of the sidewall. In an example, the angle is about 8 degrees. The honeycomb sheet can be coated with a magnetic, composite coating to increase electromagnetic shielding. An example coating includes magnetic multi-granular nanoclusters (MGNC) and multi-walled carbon nanotubes (MWCNT). A base layer can be attached to the honeycomb sheet for mechanical stability and additional absorption. The device is suitable for radar absorbing materials (RAM) for aerospace and military applications.
