Development of E Waste based Composite Microwave Absorbing Material

Microwave absorbing materials (MAMs) are widely researched due to their use in many practical applications including both civil and defense sectors. Irrespective of the humongous efforts various researchers, development a wide bandwidth, thin coating thickness, low-cost microwave absorber is still challenging task. The existing have not been able meet all specifications together at once require trade-off performance parameters. In this paper, we empirically corroborated cost-effective technique using E-waste material for synthesising composite MAM. It herein shown that addition different wt% copper, graphite, titanium dioxide successfully resulted enhanced absorption altered electrical properties suitable absorption. multilayering with help genetic algorithm has also used broaden bandwidth. As result, three-layer MAM total thickness 3.2 mm synthesised showing wideband bandwidth 8.47 GHz frequency range from 6.92 15.39 GHz. results suggested can be drastically improved by appropriately tailoring parameters such as permittivity permeability.
