This paper mainly discusses penetrable scattering problem with Robin kernel , the problem can be attributed to the following mixed boundary value problem : k_j gt ; 0 , j = 0,1 ; μ gt ; 0, the λ complex-valued function , Re ( ? ) ≤ 0 , an η is H ( ? ) lder ' continuous function , and ( ? ), η ( x ) ≠ 0 , ( ? ) Research on this issue is divided into two areas : First, the the positive scattering problem ; inverse scattering problem known scattering body shape , by the far-field scattered wave resistance coefficient η . These two aspects are based on the boundary integral equation .
