论文摘要
本文重新定义并扩展了一些有关新的光学定理以及有损培养基吸收的物理界限的最新分析结果。该分析对于任何线性散射器(例如天线)有效,该分析包括任意材料(Bianisotropic等)和任意几何形状,只要散射器由嵌入在有损背景介质中的球形体积限制。这里重新重新安装了相应的公式,并扩展了磁性和介电背景介质。还为散射和灭绝的相应边界提供了显式推导,公式和讨论。包括有关60 GHz通信带中最佳微波吸收和散射的数值示例,以说明该理论。
This paper reformulates and extends some recent analytical results concerning a new optical theorem and the associated physical bounds on absorption in lossy media. The analysis is valid for any linear scatterer (such as an antenna), consisting of arbitrary materials (bianisotropic, etc.) and arbitrary geometries, as long as the scatterer is circumscribed by a spherical volume embedded in a lossy background medium. The corresponding formulas are here reformulated and extended to encompass magnetic as well as dielectric background media. Explicit derivations, formulas and discussions are also given for the corresponding bounds on scattering and extinction. A numerical example concerning the optimal microwave absorption and scattering in atmospheric oxygen in the 60 GHz communication band is included to illustrate the theory.
