摘要：We study the parametric resonance of the neutrino oscillation through the matter whose density
varies spatially. The Fourier analysis of the matter effect enables us to clarify the parametric resonance
condition, which is summarized in a frequency matching between the neutrino oscillation
and the spatial variation of the matter density. As a result, the n-th Fourier mode of a matter
density profile modifies the energy spectrum of the νμ →νe appearance probability at around the
n-th dip.
