Abstract
Optimization necessitates every feature to be scrutinized associated with enhancement for microwave absorption. So, interplay between simulation and experiment is a significant aspect to find optimal find-ings in this regard. Herein, microwave absorption characteristics of as-prepared FeWO4 and BiVO4 nano -materials were investigated by preparing mono layer and bilayer samples. For the bilayer samples, simulation technique was used to regulate microwave absorption efficiency. Using simulation technique, bilayer sample has achieved a minimum reflection loss (RLmin) of -42 dB with BiVO4 as a top layer (0.6 mm thickness) and FeWO4 as a bottom layer (0.8 mm thickness) with effective absorption Bandwidth (EAB) of 13 GHz (15-2 GHz) at 8.2 GHz frequency. The results show that the layered architec-ture of the absorbent is substantially responsible for its remarkable microwave absorption efficiency. Simulated results of the bilayer sample were also verified with experimental findings. This work provides a facile synthesis route, novel insights into the design of bilayer absorbent as well as simulation and experimental support for high-performance microwave bilayer absorber.(c) 2023 Elsevier Inc.
