“…For this purpose, the addition of MWCNTs in the composite sample can significantly change its electromagnetic properties. This is consistent with many previous investigations [17,18], and provides a simple way to reach the maximum absorption in free space using this type of ceramics. In practice, we found by successive trials that adding a small amount of MWCNTs allows us to reach a value of Im(n) inside the grey region of Fig.…”

“…In the following work, adding multi-walled CNTs (MWCNTs) to the composite material was suggested in order to increase Im(n). Even low CNT amounts (< 5 wt.%) indeed drastically affect the electromagnetic properties of a neat polymer matrix [17,18]. Hence, by varying the MWCNT content, it is possible to obtain a highly absorbing material in free space (Fig.…”

“…3). The specific MWCNT content to achieve refractive index for maximal absorption can be well predicted and controlled by use of the Maxwell Garnett mixing law [12,18] In practice, when the frequency range is fixed, the maximum of absorption is estimated, and once the corresponding composite material is produced, it is very useful to investigate the frequency dependence of the absorption coefficient of samples with various thicknesses.

“…Some of these physical mechanisms can be efficiently combined in (nano)composite materials. A number of studies [15][16][17][18][19][20] showed that nano-sized inclusions can significantly affect the electromagnetic response of composites and provide an efficient way to tune their absorbing properties.…”

Abstract-We report the modelling and characterization of microwave absorbing materials specially designed for 26-37 GHz frequency range (Ka-band).Composite materials based on carbon nanotubes/BaTiO 3 /Fe 3 O 4 in a phosphate ceramic matrix were produced, and their electromagnetic response was investigated. Both theoretical and experimental results demonstrate that this material can absorb up to 100% of the power of an incident plane wave at a normal incidence angle. The physics underlying such absorption level is discussed in terms of refractive index of the material.

Abstract-The general principles of design and development of microwave absorbing materials are discussed and analysed in respect to 26-37 GHz frequency range (Ka-band). Dispersive composite materials based on carbon nanotubes in epoxy resin matrix are produced, and their electromagnetic responses are investigated in Ka-band. Both theoretical and experimental results demonstrate that presented composites may be used as compact effective absorbers in 26-37 GHz range.

Conducting polyaniline (PANI)/cadmium sulfide (CdS) nanocomposite films were prepared by in situ chemical oxidation method. The prepared nanocomposites were characterized by fourier transform infra‐red spectroscopy, X‐ray diffraction, and scanning electron microscopy for structural and morphological analysis. The effect of CdS content on structural and morphological features of PANI matrix are discussed in detail. The frequency dependent room temperature conductivity and dielectric properties of these composites were studied by measuring various parameters in the frequency range 10–106 Hz. The role of surface modification on electrical and dielectric properties of the composites was analyzed and it was found that, the concentration of CdS in PANI matrix has a greater influence on electrical properties due to the alteration of molecular chains in PANI matrix. Among various nanocomposites so prepared, the composite with 3 wt% of CdS in PANI matrix (P3) shows better conductivity and dielectric behavior which could be of great importance in various technological applications. The possibility of these materials being used as transistors, energy storage and nano dielectric devices could be explored further. POLYM.
