论文摘要
使用商业软件在X频段中模拟了具有石墨烯斑点像素的可控制的跨表面吸收器的PlaneWave响应。每个平方的元原子都是16像素的4x4阵列，有些是用石墨烯修补的，而另一些则没有插图。像素排列在PVC皮肤上，该皮肤放置在铜支持的YIG基板上。石墨烯提供静电可控性，YIG提供磁静力可控性。我们的设计在X频段的100 MHz光谱状态下提供了等于或超过0.9的吸收性，具有360 MHz/ka磁静力控制率和1 Hz M/V静电可控性速率。值得注意的是，通过GHz范围内的石墨烯进行静电控制是新颖的。
The planewave response of a bicontrollable metasurface absorber with graphene-patched pixels was simulated in the X band using commercial software. Each square meta-atom is a 4x4 array of 16 pixels, some patched with graphene and the others unpatched. The pixels are arranged on a PVC skin which is placed on a copper-backed YIG substrate. Graphene provides electrostatic controllability and YIG provides magnetostatic controllability. Our design delivers absorptance equal to or in excess of 0.9 over a 100-MHz spectral regime in the X band, with 360 MHz/kA magnetostatic controllabity rate and 1 Hz m/V electrostatic controllability rate. Notably, electrostatic control via graphene in the GHz range is novel.
