1维等离子体光子晶体截止频率的研究
Study on the cut-off frequency of 1-D plasma photonic crystals
摘要
Abstract
In order to study the effect of the radio of micro plasma layer width to dielectric width, dielectric constant of the dielectric material, the plasma frequency and the incident angle on the cut-off frequency, the dispersion relation of one-dimension plasma photonie crystals was analyzed by means of transfer matrix method and the change rule of the cut-off frequency was put forward.The results show that plasma photonic crystals can' t completely cut off the electromagnetic wave, whose frequency is less than the plasma frequency.The cutoff frequency comes close to the frequency of plasma when the incident angle of electromagnetic wave increases.The function of modulation for plasma photonic crystals can be realized by adjusting the index mentioned above.关键词
