SIAGULORITY ANALYSIS OF SCATTERING IN A HOMOGENEONS MEDIUM

LUAN WEN-GUI(Computer Center, Academia Sinica, Beijing 100080)  
The classification and relation between analytical singularity of back wave and correspondent topological singularity of diffraction surface with zero bias in even medium are discussed and analyzed in detail. The basis is Kirchhoff integral of diffration theory. The principle is the relation between the analytical singularity of surface geometric function and topological singularity of distance function. The mathematical tool is Morse theory and real variable theory.
