介绍了一种新的偏置技术在调谐贴片频率选择表面（FSS）中的应用。该方法遵循最近开发的技术，其中有源FSS的偏置电路被蚀刻在双面基板的背面。在这种情况下，该结构由薄聚酯基板一侧的偶极子贴片和后部的偏置电路组成，电磁隐藏在贴片中。采用变容二极管来修改贴片之间的电容。该新型有源FSS结构能够在宽的频率范围内调谐带阻滤波器响应，这可以适合于诸如建筑物的EM架构的时间相关修改的应用。
The application of a novel biasing technique to tune frequency selective surfaces (FSS) made of patch elements is described. The methodology follows a recently developed technique where the biasing circuit of an active FSS is etched at the rear of a double sided substrate. On this occasion, the structure consists of dipole patches on one side of the thin polyester substrate and the biasing circuit at the rear, electromagnetically hidden by the patches. Varactor diodes are employed to modify the capacitance between the patches. The novel active FSS structure is able to tune a bandstop filter response over a wide frequency range, which could suit applications such as the time dependent modification of the EM architecture of buildings.
