报道了一种微波三频吸收体的设计、制作和测量。紧凑型单单元电池由三个嵌套的电闭环谐振器和由介质层隔开的金属接地面组成。模拟和实验结果表明，该吸波材料在4.06 GHz、6.73 GHz和9.22 GHz有三个明显的吸收峰，其吸收率分别为0.99、0.93和0.95。这种吸收体对横向电(TE)和横向磁(TM)极化的入射角范围都是有效的。三频段吸收材料具有多波段吸收、偏振不敏感和广角响应等优点，是一种很有前途的科学和技术应用吸收元件。(C)2011年美国光学学会
We report the design, fabrication, and measurement of a microwave triple-band absorber. The compact single unit cell consists of three nested electric closed-ring resonators and a metallic ground plane separated by a dielectric layer. Simulation and experimental results show that the absorber has three distinctive absorption peaks at frequencies 4.06GHz, 6.73GHz, and 9.22GHz with the absorption rates of 0.99, 0.93, and 0.95, respectively. The absorber is valid to a wide range of incident angles for both transverse electric (TE) and transverse magnetic (TM) polarizations. The triple-band absorber is a promising candidate as absorbing elements in scientific and technical applications because of its multiband absorption, polarization insensitivity, and wide-angle response.
