摘要：

The cutoff wave number of the incompressible ablative Rayleigh-Taylor instability is calculated using the physical optics approximation of the Wentzel-Kramers-Brillouin theory. It is found that a single value of the wave number k can correspond to multiple modes with different eigenfunctions and growth rates. In the -k plane the unstable spectrum is characterized by multiple branches with different cutoff wave numbers, and eigenfunctions with different number of zeros. The theory provides a formula for the cutoff wave number, valid in the regimes of interest for inertial confinement fusion capsules. © 1994 The American Physical Society.
