By means of the transfer-matrix method, the effects of parameter modulation on the quality of near-field imaging in one-dimensional photonic crystal consisting of alteately Lett-handed material and right-handed material are investigated.Based on analyses of the recovery rate and phase shift, the results show that the imaging quality is not obviously affected by the minor changes of layer thickness.In addition, by modulating the material parameters of the Lett-handed material, it is found that for both the real part and the imaginary part, the system is more sensitive to the permeability than the permittivity for the TE wave.For the TM wave, it is reverse.These properties are very useful to fabricate Lett-handed material photonic crystals in practice.
