Development of Single layered, Wide angle, Polarization insensitive Metamaterial Absorber

The simultaneous achievement of multiband absorption, polarisation-insensitive, and angularly stable absorber is a difficult job. Therefore, in this article, an efficient single-layered designed, critically analysed, fabricated, experimentally validated. proposed model incorporates eight sectors loaded circle inside the square. four discrete absorption peaks are observed at 4.4 GHz, 6.0 14.1 16.0 GHz manifesting intensities 94%, 84%, 82%, 92%, respectively. Parametric studies have been also exercised to investigate influence geometrical design variables on absorber. structure symmetrical geometry, consequence polarisation-independent behaviour. mechanism explained by analysing surface current, electric field, magnetic field distributions. Besides, complex electromagnetic parameters extracted realise phenomenon. Additionally, validate simulated results, optimal sample fabricated measured response well-matched with ones.
