Abstract Modern human civilization deeply relies on the rapid advancement of cutting‐edge electronic systems that have revolutionized communication, education, aviation, and entertainment. However, electromagnetic interference (EMI) generated by digital poses a significant threat to society, potentially leading future crisis. While numerous efforts are made develop nanotechnological shielding mitigate detrimental effects EMI, there is limited focus creating absorption‐dominant solutions. Achieving EMI shields requires careful structural design engineering, starting from smallest components considering most effective wave attenuating factors. This review offers comprehensive overview structures, emphasizing critical elements design, mechanisms, limitations both traditional shields, common misconceptions about foundational principles science. systematic serves as scientific guide for designing structures prioritize absorption, highlighting an often‐overlooked aspect

Abstract The revolution of millimeter‐wave (mmWave) technologies is prompting a need for absorption‐dominant EMI shielding materials. While conventional materials struggle in the mmWave spectrum due to their reflective nature, this study introduces novel film with ultralow reflection (<0.05 dB or 1.5%), ultrahigh absorption (>70 98.5%), and superior 99.99999%) across triple frequency bands thickness 400 µm. By integrating magnetic composite layer (MCL), conductive patterned grid (CPG), double‐walled carbon nanotube (DWCNTF), specific resonant frequencies electromagnetic waves are transmitted into minimized reflection, trapped dissipated between CPG DWCNTF. design factors frequencies, such as geometry MCL refractive index, systematically investigated based on wave propagation theories. This innovative approach presents promising solution effective materials, implications mobile communication, radar systems, wireless gigabit communication.

Abstract The morphological distribution of absorbent in composites is equally important with absorbents for the overall electromagnetic properties, but it often ignored. Herein, a comprehensive consideration including component regulation, layered arrangement structure, and gradient concentration was used to optimize impedance matching enhance loss. On microscale, incorporation magnetic Ni nanoparticles into MXene nanosheets (Ni@MXene) endows suitable intrinsic permittivity permeability. macroscale, Ni@MXene increases effective interaction area waves, inducing multiple reflection/scattering effects. this basis, according analysis absorption, reflection, transmission (A–R–T) power coefficients composites, constructed realize at low-concentration surface layer, loss middle interlayer microwave reflection high-concentration bottom layer. Consequently, composite (LG5-10–15) achieves complete absorption coverage X-band thickness 2.00–2.20 mm RL min −68.67 dB 9.85 GHz 2.05 mm, which 199.0%, 12.6%, 50.6% higher than non-layered, descending respectively. Therefore, work confirms importance structure improving performance broadens design high-performance materials.

The demand of high-performance thin-film-shaped deformable electromagnetic interference (EMI) shielding devices is increasing for the next generation wearable and miniaturized soft electronics. Although highly reflective conductive materials can effectively shield EMI, they prevent deformation owing to rigidity generate secondary pollution simultaneously.
