This work aims to show the behavior of radar absorbing materials (RAM) based on magnetic metallic additives with different aspect ratios. For this, two materials, carbonyl iron, constituted of spherical iron particles, and carbon-steel filaments were used. These additives were characterized considering their morphological and structural features. X-ray diffraction analysis shows that the two additives have the same crystallographic structure, but their morphologies are quite different in microme...

There are open issues related to efficient rectifying device (diode) for effective applications on energy harvesting and detectors based on micro/nano antennas. Some technological approaches have been developed to improve diode performance at Terahertz (THz) and optical frequency regimes. Diodes based on Metal-Insulator-Metal (MIM) structure is one of the best candidates for this task, mainly due to its relative simple architecture, as well as its capability to achieve high frequency operations....

Multifunctional composites combine structural and other physicochemical properties, with major applications in aeronautical, space, telecommunication, automotive, and medical areas. This research evaluates electromagnetic properties of multifunctional composites based on glass fiber woven fabric pre-impregnated with epoxy resin laminated together carbon fiber non-woven veil metalized with Ni. In this way, searching for possible application as radar absorbing structures or electromagnetic interfe...

A cylinder with 2.5m of length and 0.15 m of diameter had its RCS (radar cross section) measurement performed. Subsequently, its RCS was reduced with microwave absorbing material. It was studied what the impact to the RCS of the target after transform the cylinder coated with material into a cylindrical cavity. The absorber material behavior was evaluated under the strain of a cylindrical curvature compared to the initial characterization data held in flat surface. Thus, was obtained about 20 dB...
