研究了和中球分层媒质复透射本征值的存在性。在折射率为常数的情况下,我们证明了存在无穷多个复本征值。在和常数折射率,我们表明,如果折射率是一个整数,没有复杂的本征值,而如果折射率是一个有理数,复杂的本征值可以存在。在适当的假设下,我们还表明,复杂的特征值可以存在一个球形分层的可变折射率。
We investigate the existence of complex transmission eigenvalues for spherically stratified media in and . In with the index of refraction being constant, we show that there exists an infinite number of complex eigenvalues. In and constant index of refraction, we show that if the index of refraction is an integer there are no complex eigenvalues, whereas if the index of refraction is a rational number, complex eigenvalues can exist. Under appropriate assumptions we also show that complex eigenvalues can exist for a spherically stratified variable index of refraction.
