Depolarization-field-regulated MXene/MoSe 2 heterostructures via geometry and phase engineering for electromagnetic wave absorption

-2 absorber delivers a minimum reflection loss of -61.40 dB at 2.0 mm and an effective absorption bandwidth of 6.10 GHz. This work establishes geometry/phase co-design as an effective route for manipulating depolarization fields and interfacial charge transport in high-performance electromagnetic wave absorbing materials.
