In this paper, we show that there are many almost periodic solutions corresponding to full-dimensional invariant tori for higher-dimensional beam equations with Fourier multiplier subject to periodic boundary conditions, where the nonlinearity f is a real-analytic function near u = 0 with f(0) = f′(0) = 0. The proof is based on an improved infinite-dimensional KAM theorem.
