Abstract

Quite unexpectedly with respect to the numerical and analytical results found in literature, we establish a new range for the real parameter b for which the existence of 2π-periodic solutions of the Brillouin focusing beam equation ẍ + b(1 + cos t)x =1/x is guaranteed. This is possible thanks to suitable nonresonance conditions acting on the rotation number of the solutions in the phase plane.
