摘要： In this paper, we present an efficient method to obtain absorbers with broadened operating frequency bands. They are accomplished by using the conventional magnetic absorbing materials (MAMs) in the forms of array and mesh structures, which are similar to those in the case of frequency slective surface. The proposed approach is verified not only by simulations but also by experimental results under the normal incidence at microwave frequencies. Moreover, the wideband absorber is lighter than the conventional magnetic absorber. These results indicate that our proposed absorbing structures can be used for designing good electromagnetic absorbers.
