The quick advancement in wireless information technology, especially in the high-frequency range, has led to a new kind of pollution; electromagnetic interference (EMI). This issue has been of increasing criticality and importance in worldwide consideration. One key answer is to fabricate materials that can constrict the undesirable electromagnetic waves. The coveted properties of these materials include low reflection loss, wide attenuation band, lightweight and economic viability. In this critical review, we endeavoured to condense a logical guide to different methodologies derived in the last few years to improve EM retention utilizing multi-layered sandwich designs. The prime focus of this review is to highlight the crucial and fundamental scientific necessities and preferred standpoint of using such designs. We likewise attempt to provide the necessary outlook and direction in which the future research will continue to thrive.
