The quick advancement in the 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 pulling in worldwide consideration. One key answer is to fabricate materials that can constrict the undesirable electromagnetic waves. The coveted properties of these materials incorporate low reflection loss, wide attenuation band, lightweight and economic viability. In this talk, the logical guide of different methodologies received in the last few years to improve EM retention utilizing multi-layered sandwich designs is discussed. The prime focus of this talk is to highlight the crucial and fundamental scientific necessities and preferred standpoint of using such designs. A critical outlook and direction in which future research will continue to thrive are highlighted.
