Research progress in tunable metamaterial absorber
摘要
Abstract
Metamaterials have garnered significant attention in the field of electromagnetic wave absorption due to their unique electromagnetic absorption properties.However,conventional metamaterial absorbers,with their fixed structures and materials,struggle to meet the demand of dynamically controlling electromagnetic stealth for weapons and equipment in complex battlefield environments.By incorporating tunable units,the electromagnetic properties of metamaterial absorbers can be flexibly and dynamically controlled through external excitation sources.This capability plays a crucial role in enhancing the efficacy of electromagnetic stealth for weapons and equipment.In this paper,the mechanism of regulating the metamaterial electromagnetic performance is elucidated through equivalent circuit.The current research status of tunable metamaterial absorbers,which utilize active materials,dynamic structures and circuit components,is introduced in detail.To explore the application performance of tunable metamaterial absorbers,the existing bottleneck issues in current research,such as control range and response speed are also discussed.Furthermore,the future development direction is extensively explored from the aspects of intelligent perception control,adaptive adjustment optimization,networked collaborative control,and self-powered energy supply,providing a valuable reference for the continued advancement and application of tunable metamaterial absorbers.关键词
