With the development of upgrading of intelligent equipment, it is difficult to meet the boosting requirement in the smart and intelligent systems with traditional electromagnetic response materials. By manipulating the intrinsic physical parameters or changing structural design and parameters of stealth materials, the electromagnetic response and resonance peaks were shifted, which lead to frequency and functional variations and in turn impacted the ability to response electromagnetic waves. In the short review, a brief framework based on the four hierarchical structures, including materials, structures, devices and systems, was discussed. By simply summarizing some typical studies, anticipation on the design, manufacturing, integration, mechanism and evaluation was also imaged, aiming to developing new-concept electromagnetic materials and structures from various perspectives. These efforts are also expected to develop advanced electromagnetic devices and systems with design and application support and promote the development and application of intelligent product and system.
