Researchers are trying to work out how to make a
broadband response metamaterial absorber (MMA). Electromagnetic (EM)
waves that can pass through the atmosphere and reach the ground are most
commonly used in the visible frequency range. In addition, they are
used to detect faults, inspect tapped live-powered components,
electrical failures, and thermal leaking hot spots. This research
provides a numerical analysis of a compact split ring resonator (SRR)
and circular ring resonator (CRR) based metamaterial absorber (MMA)
using a three-layer substrate material configuration for wideband
visible optical wavelength applications. The proposed metamaterial
absorber has an overall unit cell size of 800 nm × 800 nm × 175 nm in
both TE and TM mode simulations and it achieved above 80% absorbance in
the visible spectrums from 450 nm to 650 nm wavelength. The proposed MA
performed a maximum absorptivity of 99.99% at 557 nm. In addition, the
steady absorption property has a broad range of oblique incidence angle
stability. The polarization conversion ratio (PCR) is evaluated to
ensure that the MMA is perfect. Both TM and TE modes can observe
polarization insensitivity and wide-angle incidence angle stability with
18° bending effects. Moreover, a structural study using electric and
magnetic fields was carried out to better understand the MMA’s
absorption properties. The observable novelty of the proposed
metamaterial is compact in size compared with reference paper, and it
achieves an average absorbance of 91.82% for visible optical wavelength.
The proposed MMA also has bendable properties. The proposed MMA
validation has been done by two numerical simulation software. The MMA
has diverse applications, such as color image, wide-angle stability,
substantial absorption, absolute invisible layers, thermal imaging, and
magnetic resonance imaging (MRI) applications.
