We theoretically study the electron transport properties for two coupled single-walled carbon nanotube quantum dots connected to metallic electrodes under the irradiation of an exteal electromagnetic field at low temperatures.Using the standard nonequilibrium Greens function techniques,we examine the time-averaged transmission coefficient and linear conductance.It is shown that by some numerical examples,the photon-assisted inter-dot coupling causes Fano resonance and the conductance of the system is sensitive to the exteaJ field parameters.The transport dependence on the exteal field parameters may be used to detect the high-frequency microwave irradiation.
