逆散射理论中修正的电磁传输本征值

Modified electromagnetic transmission eigenvalues in inverse scattering theory

Samuel Cogar, Peter Monk

摘要:

反问题中最近的一个感兴趣的问题是研究由散射理论产生的本征值问题及其在材料无损检测中作为目标特征的潜在用途。朝着这个追求,我们引入了一个新的本征值问题相关的麦克斯韦方程组,是从测量的散射数据的比较,一个非标准的辅助散射问题。这种选择的辅助问题允许应用的正则性结果麦克斯韦方程组,以表明相关的内部传输问题具有Fredholm属性,这是用来建立的特征值是离散的。我们调查这类新的本征值的属性,并表明,本征值可以确定从测量的散射数据,最后一个简单的演示这一事实。

英文摘要:

A recent problem of interest in inverse problems has been the study of eigenvalue problems arising from scattering theory and their potential use as target signatures in nondestructive testing of materials. Towards this pursuit we introduce a new eigenvalue problem related to Maxwell's equations that is generated from a comparison of measured scattering data to that of a non-standard auxiliary scattering problem. This choice of auxiliary problem permits the application of regularity results for Maxwell's equations in order to show that a related interior transmission problem possesses the Fredholm property, which is used to establish that the eigenvalues are discrete. We investigate the properties of this new class of eigenvalues and show that the eigenvalues may be determined from measured scattering data, concluding with a simple demonstration of this fact.
