Abstract： This paper investigates optical transport in metamaterial waveguide arrays （MMWAs） exhibiting Bloch-like oscilltions （BLOs）. The MMWAs is fabricated by laterally combining metal dielectric layers in a Fibonacci sequence.By mapping the field distribution Gaussian wave packets in these arrays， we directly visualize the mechanical evolution in a classical wave environment.Three distinct oscillation modes are observed at different incident positions in the ninth-generation Fibonacci structure， without introducing thickness or refractive index gradient in any layer. Additionally， the propagation period BLOs increases with a redshift the incident wavelength for both ninth- tenth-generation Fibonacci MMWAs.These findings provide a valuable method for manipulating BLOs fer new insights into optical transport in metamaterials， with potential applications in optical device wave control technologies.
