Abstract
Tunneling effects for a nonlinear barrier of a constant height is studied analytically by the small-amplitude method. Explicit formulas for the field inside and outside the barrier are derived. The special case of a low barrier nontransparent to a linear medium and transparent to a nonlinear one is studied. The amplitude range of the obtained results is extended on the basis of the numerical analysis performed.
