Abstract
/N-doped pyrolyzed corn husk (PCH) demonstrated outstanding electromagnetic interference shielding effectiveness (EMISE) based on its absorption covering the entire K-band frequency with ≈100% shielding, a fascinating reflection loss (RL) of -95.32 dB at 21.28 GHz, and outstanding efficient bandwidth (EBW) of 7.61 GHz (RL ≤ -10) with a thickness of only 0.45 mm. It is noteworthy that the energy-saving features of the final composites were precisely investigated using an infrared (IR) absorption approach.
