Broadband microwave metamaterial absorber based on magnetic periodic elements
JOURNAL OF PHYSICS D-APPLIED PHYSICS(2020)
摘要
In this paper, we propose and demonstrate a broadband microwave absorber based on magnetic metamaterial structure elements. We deploy FeCo soft magnetic composite with droplet shape as the primary resonant element. By investigating the resonant modes and the coupling between periodic unit-cells and the incident microwave, it is found the intrinsic magnetic susceptibility of the magnetic elements could make the magnetic field confined in the magnetic element, and thus results in a broadband microwave absorption. Our work provides a new approach to realize broadband microwave absorbers based on hybrid absorption mechanisms, including dielectric resonator effect, one quarter wavelength resonance effect, and grating effect.
