We have studied a hybrid system of a one-dimensional coupled-cavity waveguide with a two-level system inside which was subjected to a external periodical field. Using the extended-Hilbert-space formalism, the time-dependent Hamiltonian is reduced into an equivalent time-independent one. Via computing the Floquet-Green's function, the Zeno-anti-Zeno crossover is controlled by the driving intensity and frequency and the detuning between the cavity and the two-level system.
