Abstract
ABSTRACT The increasing demand for lightweight electromagnetic wave (EMW) absorbing monoliths, particularly those capable of absorbing both low‐frequency and broadband EMWs, presents a significant challenge. While dielectric nanostructured aerogels have demonstrated high potential and advancements, a gap remains in the development of aerogel‐based EMW absorbers to achieve effective low‐frequency and broadband absorption. Here, we present a multiscale engineering strategy for fabricating aerogel‐metamaterial hybrids, addressing key challenges such as broad bandwidth, low‐frequency absorption, and high load‐bearing capacity. The proposed absorber consists of a simulation‐assisted additive‐manufactured…
