Abstract
We briefly tackle the following concepts in the Demkov-Ostrovsky (DO) nodeless sector: i) orbital impedance, ii) orbital capacity, iii) clos eness to reflectionless-ness. Moreover using previous supersymmetric r esults for the DO problem, a strictly isospectral effect in the DO orb ital impedances is discussed and explicit plots are displayed for the Maxwell fisheye lens. This effect, though rather small, is general, th at is it may apply to any focusing structure.
