Let Ta,φ be a Fourier integral operator defined by the oscillatory integral Ta,φu(x) =1/(2π)n ∫Rn eiφ(x,ξ)a(x,ξ)(u)(ξ)dξ,where a ∈ S(e),me,δ and φ ∈ Φ2,satisfying the strong non-degenerate condition.It is shown that if0 ＜ (e)≤ 1,0≤ δ ＜ 1 and m≤ (e)2-n/2,thenTα,φ is a bounded operator from L∞(Rn) to BMO(Rn).
