Abstract

The common practice of applying reflection loss to material is incorrect as it can only be applied to film. Also the dominant theory of impedance matching should be replaced by wave cancellation theory. Here, we show that experimental data obtained from microwave absorption by the film of the titled composite can be successfully analyzed theoretically from our new theories. Formulae for the scattering parameters s₁₁ and s₂₁ of the film have been derived based on the wave addition model which clearly differentiates between microwave absorption mechanisms from interface and film. The experimental values, the patterns from s₁₁ and s₂₁, and the relationships between the patterns from the experimental values have been reproduced and interpreted both quantitatively and qualitatively from the new perspective. This specific new analysis for the verification of the new theory involving a large data set provides a clear indication that the conclusions obtained are not only valid for one unique system but are of general applicability. Thus, the new theory has been verified and can be used to reveal the mechanisms of microwave absorption by material and device. The successful interpretations are contrasted with the inadequacies of previous applied methods involving reflection loss and impedance matching.

摘要

将反射损耗应用于材料的常见做法是不正确的，因为它只能应用于薄膜。阻抗匹配的主导理论也应该被波抵消理论取代。在这里，我们表明可以从我们的新理论中成功地分析从有标题的复合材料的薄膜吸收微波获得的实验数据。薄膜散射参数s ₁₁和s ₂₁的公式是基于波加法模型推导出来的，该模型清楚地区分了界面和薄膜的微波吸收机制。实验值，s ₁₁和s _{21 的模式}，并且从新的角度对来自实验值的模式之间的关系进行了定量和定性的复制和解释。这种用于验证涉及大数据集的新理论的特定新分析清楚地表明，所获得的结论不仅对一个独特的系统有效，而且具有普遍适用性。因此，新理论已得到验证，可用于揭示材料和器件吸收微波的机制。成功的解释与以前应用的方法的不足形成对比，这些方法涉及反射损耗和阻抗匹配。
