We employ the singular sources method introduced in [4] to solve an inverse transmission scattering problem for the Helmholtz equation 4u þ j 2 u ¼ 0 in R m n D or D, respectively, where the total field u satisfies the transmission conditions u þ ¼ u À and @uþ @m ¼ b @uÀ @m on the boundary of some domain D with some constant b. The main idea of the singular(More)
