在这项工作的第二部分，数值解，使用一个合理的估计标签IC阻抗，显示提供准确的估计标签天线的散射效应。一个大大简化的标签阵列的散射理论也提出了，使用希尔和Cha和简化的通用标签天线模型后的Floquet近似的阐述，允许半定量的结果与基本的解析表达式，没有迭代复杂的阵列。结果提供了一个定性的确认，标签状天线阵列产生足够强的散射影响的能力，电力和读取标签，特别是当端射照明。
In Part II of this work, a numerical solution, using a reasonable estimate for the tag IC impedance, is shown to provide accurate estimates of the scattering effects of tag antennas. A greatly simplified scattering theory for tag arrays is also presented, using an elaboration of the Floquet approximation after Hill and Cha and a simplified generic tag antenna model, allowing semi-quantitative results for complex arrays with elementary analytic expressions and no iteration. The results provide a qualitative confirmation that arrays of tag-like antennas produce sufficiently strong scattering to impact the ability to power and read a tag, particularly when end-fire illumination is employed.
