THE SPECTRAL FUNCTIONS OF SELF-SIMILAR STRUCTURES
自相似结构的谱函数

IB this paper, two self-similar plane structures are designed, the corresponding diffraction screens arc made and its Fraunhofer pattern are obtained. Based on the view point of successive re-production, the spectral recurrence formulas are deduced, and aseries of spectral functioa curves are drawn. Finally we discuss some characters of the curves. This investigation provides an optical analogue method for researching practical self-similar problems.
