Abstract Radar-absorbing materials (RAM) have been widely used in civilian areas for electromagnetic interference shielding and in the defense sector for radar wave stealth. The thickness of radar-absorbing materials is one of the important parameters affecting their performance. This paper analyzes the relationship between the absorbing performance of radar-absorbing materials and thickness based on transmission line theory. Through theoretical derivation and simulation verification, the concepts of optimal usage thickness and cutoff thickness of materials are derived. The research results ha

Resumen

Carbon foams were prepared by a polymer sponge replication method and their microwave absorbing properties were investigated in this paper. It was found that the electric conductivity of carbon foams increases quickly with the improvement of carbonization temperatures. Moreover, the electric conductivity of carbon foams strongly affects their microwave absorbing performances. As the electric conductivity increases from 0.02 S/m to 1.03 S/m, the dominant electromagnetic behavior of carbon foams changes from transmission to reflection with regard to the incident electromagnetic wave.

Resumen

A novel structural radar absorbing materials (SRAM), which give the new absorbing microwaves function to the normal resin-base composites, were prepared. The dynamic compressive tests of SRAM were carried out along both in-plane and normal plane directions of composites by means of the Split Hopkinson Pressure Bar (SHPB). In compressive test along in-plane direction, failure happened at the interface between fiber and matrix. Fracture mode and mechanism was proposed to explain these results. The adding of magnetic absorbing particles resulted in the deterioration of the compressive properties.

Resumen

The development of technologies that can rival the devices used by other countries in the defense industry, and more importantly, can disable their devices is becoming more critical. Radar absorber materials (RAM) make the detection of the material on the radar difficult because of absorbing a part of the electromagnetic wave sent by the radar. Considering that radar is one of the most important technologies used in the defense industry, the production of non-radar materials is vital for all countries in the world.

Abstract The rapid increase in electromagnetic interference has received a serious attention from researchers who responded by producing a variety of radar absorbing materials especially at high gigahertz frequencies. Ongoing investigation is being carried out in order to find the best absorbing materials which can fulfill the requirements for smart absorbing materials which are lightweight, broad bandwidth absorption, stronger absorption etc. Therefore, this article introduces the electromagnetic wave absorption mechanisms and then reveals and reviews those parameters that enhance the absorpt

Resumen

Silicon carbide (SiC) has good chemical resistance, excellent mechanical properties, thermal conductivity, especially in extreme conditions of application, and has proved to be a very promising electromagnetic absorption material. However, single silicon carbide cannot meet the increasing demand for high performance of absorbing materials. It has become an important research direction to combine it with other absorbing materials to improve its absorbing performance. In this study, a composite absorber material was prepared by 50 wt.% micron-sized beta-silicon carbide (β-sic) powder, mixed with

Resumen

A widely used genetic algorithm (GA) is endorsed to improve the design of a multilayer microwave radar absorbing material (MMRAM) which shows good absorption of radar waves over a broad frequency range. In this research, the authors have used genetic algorithm based on MMRAM which plays an important role in defense and civil applications. The scope of multilayer microwave radar absorbing material (MMRAM) is that it can absorb radar signals and reduce or eliminate their reflection. Its primary use is in defense and certain commercial enterprises. The multilayer RAM design demands the superiorit

Resumen

Coatings of alumina and titania of two different compositions and at different angles has been developed using plasma spraying method. The surface and cross-sectional morphological characterizations of Al<sub>2</sub>O<sub>3 </sub>and Al<sub>2</sub>O<sub>3</sub>/ TiO<sub>2 </sub>powders and coatings were done by scanning electron microscope (SEM). The microwave absorbing properties of developed coatings has been observed in X-band (8.2-12.4GHz) frequency range using network analyzer. The reflection loss of Al<sub>2</sub>O<sub>3</sub> is -19dB at 10.495GHz with a bandwidth of 0.32Hz

Resumen

In recent decades, the capabilities of detection equipment for both aerodynamic and ground (surface) targets have increased dramatically. Therefore, it is of particular importance to reduce the radar visibility of weapons. The antenna systems of weapons and military equipment are one of the main elements that demask them. One of the ways to reduce the radar visibility of antenna systems is to use radio-absorbing materials. Reducing the radar visibility of a mirror antenna by giving it a special shape is unacceptable, since the shape of the mirror is determined by the need to form the direction

Resumen

In the past decade, new materials have been developed based on the physical and chemical properties of carbon nanotubes. The combination of polyaniline with multiwall carbon nanotubes results in a new functional material with advantageous electromagnetic properties. The objective of this study was to produce a radar absorbing structure consisting of glass fiber woven fabric impregnated with a formulation containing carbon nanotubes, polyurethane resin, with or without polyaniline. A different formulation was used for each woven sheet (multilayer structure). The electromagnetic properties of th

Resumen

The three common frequency selective surface (FSS) structure, i.e. ring, crosses and Y-aperture which have the same center frequencies are designed, then the three FSS structures are placed at absorbing materials to form complex absorbing structures which are simulated by means of spectral domain approach. Therefore, the effects of different FSS on the characteristics of absorbing materials are studied and the influence laws are given. This research offers reference to element selection for the application of common FSS to absorbing materials.

Resumen

Ferrite-containing polymer composites are of great interest for the development of radar-absorbing and -shielding materials (RAMs and RSMs). The main objective of RAM and RSM development is to achieve a combination of efficient electromagnetic wave (EMW) absorption methods with advantageous technological and mechanical properties as well as acceptable weight and dimensions in the final product. This work deals with composite RAMs and RSMs containing spinel-structured ferrites. These materials are chosen since they can act as efficient RAMs in the form of ceramic plates and as fillers for radar
