Abstract
It is a very difficult job to design a cost-effective and efficient microwave absorber for low observable applications. The simultaneous achievement of minimum absorber thickness with wide absorption bandwidth (RC ≤ −10 dB) is the main concern of this study. This target is achieved by the application of electronic waste (E-waste) composite and metamaterial structure at X-band. A critical analysis of microwave absorption properties of the absorber is carried out by the application of a split-ring resonator (SRR), ring, plus, and square patch geometries. The effect of E-waste composite layer thickness, layer position, conducting geometry dimensions is carried out in order to achieve an optimal microwave absorber. E-waste absorber loaded with SRR geometry is found to possess interesting microwave absorption properties in terms of wide absorption bandwidth and lower thickness.
