The band structures and optical properties of AB-stacked multilayer graphene are calculated using the tight-binding model and gradient approximation. For nL-layer AB-stacked graphene, there are n2L excitation channels at both the low and middle frequencies. However, in the excitation spectra, nL (nL - 1) peaks exist at the low frequency for even-layer (odd-layer) systems, and one-shoulder and nL peaks at the middle frequency. With increasing nL, the differences in the spectra between the odd and even layers are reduced. When nL increases to 30 (50), the spectra of 2D and 3D systems are almost identical at the middle (low) frequency.
