Researchers are trying to work out how make a broadband response metamaterial absorber (MMA). Electromagnetic (EM) waves that can pass through the atmosphere and reach ground most commonly used in visible frequency range. In addition, they detect faults, inspect tapped live-powered components, electrical failures, thermal leaking hot spots. This research provides numerical analysis of compact split ring resonator (SRR) circular (CRR) based (MMA) using three-layer substrate material...
