Some distributed oscillatory systems have irregular, in particular, Morse, critical points, in addition to the regular points of the spectrum. Let us define oscillations near a Morse critical point as a linear bistable element (LBE). In this paper, we consider the formation and properties of LBEs in electrodynamics.
