Abstract: Utilizing Floquet scattering method,the paper investigates the electronic density of states (DOS) and renormalized resistance of multiwall carbon nanotubes  under the irradiation of the terahertz electromagnetic fields.With the irradiation frequency of the external field remaining unchanged,the system DOS is observed to increase at first and then decrease oscillately,while the renormalized resistance of the system firstly decreases rapidly and then increases osicllately with the increasing irradiation intensity.On the other hand,the situation for the unchanged irradiation intensities is some what different,the system DOS increases quickly to a saturation value and then decreases oscillately and slowly,the renormalized resistance decreases urgently to be nearly 0.10 and then increases slowly.

Key words: multiwall carbon nanotubes, Floquet scattering method, terahertz electromagnetic field, electron density of states, renormalized resistance
