  1. First, in virtual of identification of flaws is a typical of in - verse problems, proceeding from time - harmonic electromagnetic maxwell ' s equa - tion and helmholtz equation, the uniqueness and existence of direct scattering problems including the numerical algorithms of diverse of boundary conditions is given. second, the uniqueness and existence of inverse scattering problems and the theory of ill - posed integral equation are briefly looked back upon. finally, indicator function method for boundary identification is set up under all kinds of boundary conditions for inverse scattering of homogenous and inhomogenous objects, meanwhile, the proof of possibility for near - field measurements and nu - merical simulation are given

    由於缺陷的識別是一類典型的反問題,因而首先從時電磁maxwell方程和helmholz方程出發,具體地闡述了求正散射問題的有關方法,包括各種(夾雜)邊界條件下的數值法,就的存在性唯一性給予了肯定的回答;隨后對逆散射問題的理論作了簡的回顧,包括的唯一性以及非性不適定積分方程的處理等;然後對均勻介質和非均勻介質的逆散射問題建立了在各種邊界條件下的邊界識別的指示函數方法,鑒于近場數據獲得的重要性,對近場測試時邊界識別的方法給予了相應的證明,並且實現了數值模擬。
