Abstract. A transmission matrix method (TMM) commonly used for modeling the electromagnetic properties of multilayered biopolymer/conductive nanoparticle composites is presented, which predicts the behavior of the experimental results of the electromagnetic shielding effectiveness of a deoxyribonucleic acid-silver nanoparticle composite but falls short for accurately predicting the absolute shielding effectiveness. The versatility of the model can handle metamaterials, various incident angles, both TE and TM polarizations, and single and multilayer structures with complex and dispersive permittivity and permeability. We present the simulated results for a single-layer slab using the TMM along with the experimental results. Parametric studies are conducted with the model to investigate the reflection and transmission performance for single-layer slabs by varying the loss tangent, dielectric constant, incident angle, and thickness parameters.

DNA导电纳米粒子复合材料电磁屏蔽效能实验结果的传输矩阵法建模

摘要。介绍了一种常用于模拟多层生物聚合物/导电纳米颗粒复合材料的电磁特性的传输矩阵方法 (TMM),该方法可以预测脱氧核糖核酸-银纳米颗粒复合材料的电磁屏蔽效果的实验结果的行为,但不能准确预测预测绝对屏蔽效能。该模型的多功能性可以处理超材料、各种入射角、TE 和 TM 极化以及具有复杂和色散介电常数和磁导率的单层和多层结构。我们展示了使用 TMM 的单层板的模拟结果以及实验结果。
