“…The inclusion of Ba(Fe 1−x DI x ) 12 O 19 powders into the polymer matrix opens up new application possibilities of such composites [22][23][24][25][26][27]. The advantages of polymer-bonded composites with BaM are: their ability to be molded into complex shapes and sizes; low weights and relatively low prices; sharply reduced dielectric loss compared to bulk ferrites; and stable microwave absorption properties due to the domination of NFMR absorption in the loss mechanism of the absorbing ferrite materials.…”

The paper describes preparation features of functional composites based on ferrites, such as “Ba(Fe1−xGax)12O19/epoxy,” and the results of studying their systems; namely, the correlation between structure, magnetic properties and electromagnetic absorption characteristics. We demonstrated the strong mutual influence of the chemical compositions of magnetic fillers (Ba(Fe1−xGax)12O19 0.01 < x < 0.1 solid solutions), and the main magnetic (coercivity, magnetization, anisotropy field and the first anisotropy constant) and microwave (resonant frequency and amplitude) characteristics of functional composites with 30 wt.% of hexaferrite. The paper presents a correlation between the chemical compositions of composites and amplitude–frequency characteristics. Increase of Ga-content from x = 0 to 0.1 in Ba(Fe1−xGax)12O19/epoxy composites leads to increase of the resonant frequency from 51 to 54 GHz and absorption amplitude from −1.5 to −10.5 dB/mm. The ability to control the electromagnetic properties in these types of composites opens great prospects for their practical applications due to high absorption efficiency, and lower cost in comparison with pure ceramics oxides.

“…They have been an increasing degree of interest which is still growing exponentially today [2 -5]. The hexagonal ferrites are promising materials for the production of microwave absorbing composite materials [6,7]. When EM waves are irradiated into magnetic materials, a natural resonance (ferromagnetic resonance without an applied magnetic field) occurs, thus achieving the attenuation of EM waves.…”

In this study, Co0,7Zn1,3W powders were synthesized and investigated at the microwave region. The solid-state reaction method and self-propagating high-temperature synthesis were used to production of the two kinds of hexaferrite powders. The high-frequency magnetic properties under temperature effect have been studied. It is show, that there is a nonlinear dependence on temperature within the 0 – +40 °C temperature range.

“…The application of nanotubes as independent materials is troublesome, because they possess volatility and low bulk density. For this reason, nanotubes are used as filler in the manufacture composite [6][7][8], which can be used to solve problems of electromagnetic compatibility and radio components. The microwave properties of a composite are described by the frequency dependence of complex permittivity ( ) ( ) ( )…”

There is a growing demand for light and radar absorbing materials in both commercial and military purposes. In this paper, microwave properties of polimer based composites containing multiwalled carbon nanotubes used as fillers have been analyzed. The multiwall carbon nanotubes used in the composite were about 9.4 nm in diameter. The results show that the ultrasonic treatment modifies the dielectric properties of the composite. Both real and imaginary permittivity of composites is 2 times more than ordinary example after sonicating for 3 minutes.
