摘要

研究了波导捕获模式及其存在性和渐近线。简单特征值(嵌入在连续光谱中)在波导填充的小扰动下显示不稳定,与孤立特征值的行为相反。

The embedded eigenvalues of the waveguide
Waveguide trapped modes, their existence and asymptotes are studied. Simple eigenvalues (embedded in the continuous spectrum) are shown not to be stable under a small perturbation of the waveguide filling, contrary to the behavior of isolated eigenvalues.
