We present the study of non-diffracting Mathieu beams, also known as Pendulum beams. In previous studies we studied pendulum beams that corresponded to stationary states of the quantum pendulum. In this work we present the results of superpositions of pendulum states with phases correlating to the time evolution of the quantum states of the pendulum. Thus, as a function of time, the quantum probability extracted from the beams mimicked the classical pendulum, liberating or rotating depending on whether the states involved in the superposition were below the potential barrier or above it. We also study the simple pendulum states for large values of the potential barrier.
