“…Dielectric resonator theory provides a description of the variational resonant modes, especially for dielectric resonators with complex shapes [173,174]. To select suitable relative permittivity, geometrical shapes, and sizes of dielectric blocks, various resonance modes can be stimulated at required frequencies [175,176]. Resonance enhanced displacement current are usually found in high permittivity dielectric resonators, when the electric size of the resonator is correlated with the wavelength of the incident electromagnetic waves.…”

Artificially-structured functional materials (AFMs) are artificial media that combine the advantages of nature materials and artificial structures to produce excellent and unexpected properties. Ferroelectric materials have key features in possessing spontaneous polarizations, which can be switched by using electric field, temperature, and strain. This review article attempts to provide a comprehensive insight into the current development of ferroelectric composite AFMs, and to introduce a developing subject in realizing multifield controls for tunable functional devices. Some typical ferroelectric materials and their multifield tunable mechanisms are summarized in detail. The incorporation of ferroelectric materials can yield various designs of AFMs to modulate electromagnetic waves. Recent progress of typical designs with different tuning strategies for active AFMs are illustrated and compared, including the metamaterials, metasurfaces, heterojunctions, superlattices, and their hybrid designs. This scientific subject involves interesting research topics of electromagnetism, electronics, optoelectronics, and ferroelectrics, which is significant to bring novel functionalities via multifield controls.

Frequency selective surface (FSS) has been extensively studied due to its potential applications in radomes, antenna reflectors, high-impedance surfaces and absorbers. Recently, a new principle of designing FSS has been proposed and mainly studied in two levels. In the level of materials, dielectric materials instead of metallic patterns are capable of achieving more functional performance in FSS design. Moreover, FSSs made of dielectric materials can be used in different extreme environments, depending on their electrical, thermal or mechanical properties. In the level of design principle, the theory of metamaterial can be used to design FSS in a convenient and concise way. In this review paper, we provide a brief summary about the recent progress in all-dielectric metamaterial frequency selective surface (ADM-FSS). The basic principle of designing ADM-FSS is summarized. As significant tools, Mie theory and dielectric resonator (DR) theory are given which illustrate clearly how they are used in the FSS design. Then, several design cases including dielectric particle-based ADM-FSS and dielectric network-based ADM-FSS are introduced and reviewed. After a discussion of these two types of ADM-FSSs, we reviewed the existing fabrication techniques that are used in building the experiment samples. Finally, issues and challenges regarding the rapid fabrication techniques and further development aspects are discussed.

A broadband tunable metematerial absorber is proposed and demonstrated. As demonstrated in waveguide, the absorber consists of eight U-shaped ferrite particles and a metallic ground plane. These U-shaped ferrites directly act as resonators, and when the incident electromagnetic wave and applied magnetic field are simultaneously acting on the U-shaped ferrite particles, U-shaped ferrites can produce ferromagnetic resonance (FMR). Absorption frequency of the all-ferrite absorber can be tuned by the applied magnetic field and the saturation magnetization. Simulation results show absorption above 70% in the frequency range from 8.55 GHz to 10 GHz under applied magnetic field with H 0 = 2700 Oe. By analysis, we find that the magnetic loss and dielectric loss lead to broadband absorption. The experiment test agrees well with the simulation results under different applied magnetic fields. This work provides an alternative route to realize tunable perfect absorbers with all-ferrite structures. With the artificial design of ferrite materials, the broadband tunable absorber can be designed and well serve in high power environment.INDEX TERMS U-shaped ferrite, tunable metamaterial absorber, applied magnetic field.
