论文摘要
通过简单地连接的轴向对称域的非磁性材料的数值测试比较了两个最近得出的用于麦克斯韦传播问题的积分方程。获胜的积分方程完全没有用于任何被动材料的虚假特征Wavenumbers，这也是纯粹的负介电比率和静态限制的，并且没有在非平滑表面上的错误基本频谱。尽管使用了八个标量表面密度，但它似乎也与麦克斯韦传输问题的所有其他可用的积分方程重新印象具有数值竞争力。
Two recently derived integral equations for the Maxwell transmission problem are compared through numerical tests on simply connected axially symmetric domains for non-magnetic materials. The winning integral equation turns out to be entirely free from false eigenwavenumbers for any passive materials, also for purely negative permittivity ratios and in the static limit, as well as free from false essential spectrum on non-smooth surfaces. It also appears to be numerically competitive to all other available integral equation reformulations of the Maxwell transmission problem, despite using eight scalar surface densities.
