开发了由烧结平面六角形铁氧体组成的单层吸收器。吸收体在微波频率下具有 50% 至 90% 的相对带宽。通过四分之一波长谐振器模型成功地分析了宽带特性，该模型考虑了由于 1/根 epsilon(r)mu(r) 导致的波长减小和取决于 tan delta(mu) 的谐振频移，其中 epsilon(r) 和 mu(r) 分别是谐振器材料的相对介电常数和磁导率。
Single-layer absorbers composed of sintered planar hexagonal ferrites were developed. The absorbers have 50 similar to 90 % relative band-width at microwave frequencies. The broad-band characteristics were successfully analyzed by a quarter-wavelength resonator model, which took into account both a wavelength reduction due to 1/root epsilon(r)mu(r) and a resonant frequency shift depending on tan delta(mu), where epsilon(r) and mu(r) are relative permittivity and permeability, respectively, for the resonator material.
