✦ Synopsis
For a class of standing electromagnetic waves of a special structure, the motion of the charged particles in the vicinities of nodal points is approximable by an exactly soluble dynamical model (the Schr6dinger particle driven by a rotating magnetic field). This model shows a sudden qualitative change when the field intensity/frequency ratio crosses a critical value. It implies the conversion of the nodal points from particle traps into repulsive centers. A hypothesis is thus raised that for high intensity/t?equency values, the standing wave traps can undergo a qualitative metamorphosis resembling the phase transitions.
