当需要多次迭代时，电磁带隙（EBG）结构的电磁（EM）模拟在计算上是昂贵的。本文首次提出了一种新颖的EBG结构综合方法。该方法包括三个主要的方法：电流路径近似法（CPA法），边界到边界半径（B2BR），和功率损耗法（PLM）。CPA方法基于周期性图案化的电源/接地层上的电流。CPA方法给出了EBG结构的最终尺寸为所需的阻带频率。B2BR确定在给定区域内可实现的补丁的最大数量。PLM基于传输功率计算EBG结构的隔离水平。所提出的方法已经结合在一起，合成一个EBG结构为一个给定的规范。用这些方法合成的EBG结构已被制作并通过EM模拟和测量进行了验证。EBG结构具有良好的阻带和隔离度，符合预期的技术指标
Electromagnetic (EM) simulation of electromagnetic band gap (EBG) structures is computationally expensive when multiple iterations are required. For the first time, in this paper, a novel synthesis method for designing EBG structures has been proposed. The method consists of three major approaches: current path approximation method (CPA-method), border to border radius (B2BR), and power loss method (PLM). CPA-method is based on the current flow on a periodically patterned power/ground plane. CPA-method gives a final dimension of EBG structure for a desired stop band frequency. B2BR determines the maximum number of patches implementable within a given area. PLM calculates isolation level of an EBG structure based on the transmitted power. The proposed approaches have been combined together to synthesize an EBG structure for a given specification. The synthesized EBG structure with these approaches has been fabricated and verified with EM simulation and measurement. The EBG structure has shown excellent stop band and isolation level agreements with the desired specification
