Abstract

Electromagnetic wave absorption (EMWA) materials are widely used in wireless communications and play an important role in contemporary smart economy. EMWA materials that show dielectric losses have attracted research attention owing to their unique advantages. However, previous studies have focused on material synthesis whereas few studies have systematically explained the mechanism of dielectric loss. Taking the concept of dielectric genes as the starting point and Debye relaxation model as the "compass," the dependence of the electromagnetic wave absorption at different frequencies on each dielectric parameter is introduced in detail, and a dynamic trend model is constructed for the prediction of electromagnetic wave absorption characteristics, followed by discussion of the development and future prospects of EMWA materials, providing inspiration for the design of dielectric-loss absorption materials in the future.

Keywords: Debye relaxation model; EMWA materials; dielectric genes.
