关于体积积分方程中幂的计算
On the Computation of Power in Volume Integral Equation Formulations
摘要：
我们提出了简单而稳定的公式计算功率（包括吸收/辐射，散射和消光功率）在电流为基础的体积积分方程配方。所提出的公式给出的向量矩阵向量产品的数量只发现在相关的线性系统。除了它们的效率，推导出的表达式可以保证计算功率的正性。我们还讨论了坡印廷定理的应用的情况下，源沉浸在耗散材料。对散射和辐射基准情况下的分析和数值方法得到的结果进行了验证的公式。
英文摘要：
We present simple and stable formulas for computing power (including absorbed/radiated, scattered and extinction power) in current-based volume integral equation formulations. The proposed formulas are given in terms of vector-matrix-vector products of quantities found solely in the associated linear system. In addition to their efficiency, the derived expressions can guarantee the positivity of the computed power. We also discuss the application of Poynting's theorem for the case of sources immersed in dissipative materials. The formulas are validated against results obtained both with analytical and numerical methods for scattering and radiation benchmark cases.
