Design of Broadband Radar Absorbing Materials Using Particle Swarm Optimization
The design of planar multi-layer coatings with high absorption for a desired frequency and angle range is presented. The design technique is based on Particle swarm optimization (PSO). PSO is an evolutionary optimization algorithm based on the bird fly. Several design cases are presented. Numerical results that are compared with the existing in the literature show the advantages of this approac...
متن کاملImproving Radar Absorbing Capability of Polystyrene Nanocomposites: Preparation and Investigation of Microwave Absorbing Properties
Microwave absorbing materials are usually designed to solve protection against electromagnetic interference in wireless communication systems and high frequency circuit mechanisms. In this research polystyrene (PS) nanocomposites containing various nano-fillers were successfully synthesized. The novelty of this work is comparing of three various nanostructures: non-metallic conductive graphene ...
متن کاملSimple Method for the Preparation of Fe3O4/MWCNT Nanohybrid as Radar Absorbing Material (RAM)
We have successfully prepared Fe3O4/MWCNT nanohybrid with a very simple and economical method. Multi-Walled Carbon NanoTubes (MWCNT) encapsulated with Fe3O4 nanoparticles were synthesized via pyrolyzing of ferrocene. The sample was characterized with XRD, TEM and Vibrating Sample Magnetometer (VSM). Also, Permeability (µ) and Permittivity (ε) were...
متن کاملRadar Absorbing Nanocomposites Based MultiLayered Graphene Platelets/Epoxy
Graphene nanostructures were synthesized by Hummer method. 1, 3, 5 and 7 wt% of graphene nanostructures were suspended in certain amount of acetone on a mechanical stirrer and stirred then added to epoxy resin. After 4 hours, solution and Graphene platelets (GPs) were prepared. Nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM ), Fourier transform i...
متن کاملGraphene-enabled electrically switchable radar-absorbing surfaces.
Radar-absorbing materials are used in stealth technologies for concealment of an object from radar detection. Resistive and/or magnetic composite materials are used to reduce the backscattered microwave signals. Inability to control electrical properties of these materials, however, hinders the realization of active camouflage systems. Here, using large-area graphene electrodes, we demonstrate ...
