Abstract：With the successive emergence of various new detection systems，the development of magnetic shielding field hasbecome increasinglyurgent.Conventional absorbers，which utilizeresistive orresonant structures toabsorb electromagnetic waves，stillsuffer from issues such asanarrowabsorptionbandwidthand lowabsorption efficiency.Metamaterial absorbers，with their outstanding absorption performance and lightweight structures， demonstrate broad application prospects in the magnetic shielding field.To address these challenges，this paper introduces magnetic ferite materialsand slow-wave structures，combining them to form metamaterials with special functions.Research and design of UHF-band wave absorbers based on ferrite materials are conducted.
