Abstract Excessive electromagnetic pollution caused by waves can interfere with the normal use of electronic devices or cause unnecessary damage to human health. Although conductive polymer composites (CPCs) are used replace traditional metals as an effective strategy for managing undesirable waves, CPCs have a non‐negligible trade‐off in enhancement interference (EMI) shielding effectiveness and absorption coefficient because their reflection‐dominated EMI mechanism. Therefore, alleviate secondary pollution, absorption‐dominated asymmetric structures urgently needed. Recently, structural designs advanced significantly, but seldom been summarized discussed detail. Consequently, this review first systematically summarizes current progress after brief clarification about necessity configuration structure design. Afterward, various fiber, layered, porous, composite described. Besides, versatility is briefly introduced. Finally, challenges prospects proposed guide future advancement field.

Abstract A reasonable construction of hollow structures to obtain high‐performance absorbers is widely studied, but it still a challenge select suitable materials improve the low‐frequency attenuation performance. Here, Fe 3 O 4 @C@NiO nanoprisms with unique tip shapes, asymmetric multi‐path cavity, and core–shell heteroepitaxy structure are designed synthesized based on anisotropy intrinsic physical characteristics. Impressively, by changing load NiO, composites achieve strong absorption, broadband, absorption: reflection loss −55.8 dB absorption bandwidth 9.9 GHz covers both low high frequency (2.9–6.1 11.3–18 GHz). The constructed anisotropic heterointerface can optimize impedance matching for (3.8–7.9 GHz) almost completely covering 5G band. Especially, influence path interface polarization ferromagnetic coupling behavior revealed through simulation electric magnetic field distribution using High‐Frequency Structure Simulator (HFSS). In addition, HFSS shows that Radar Cross‐Sectional (RCS) value absorber at any angle <−10 m 2 , which meets complex requirements in practical application. This research paves new way development efficient composition design.

Electromagnetic interference (EMI) shielding fibers are crucial in practical uses for their flexibility and one-dimensional form. However, application is limited by poor compatibility between EMI components fiber substrates, high electromagnetic wave reflectivity. Herein, a core/shell-structured introduced, featuring core of Ga-In-Sn-Zn alloy, Carbopol, air bubbles, shell ionogel formed from copolymerized acrylamide acrylic acid. A single achieves total effectiveness ∼35 dB within the 2-18 GHz range, which increases to ∼70 when three stacked. Remarkably, demonstrates enhanced performance following stretching recovery. Additionally, it exhibits excellent impedance matching, with reflection power coefficient as low 0.14 at 10 GHz. The fiber's mechanism encompasses shielding, absorption shielding─attributable conduction loss polarization loss─and multiple shielding. Furthermore, shows potential strain sensor. This research offers an effective strategy creating flexible capabilities EM reflection.
