【Abstract】 The generalized electromagnetic reciprocity theorem is deduced by the language of differential forms. As applications, the generalized electromagnetic reciprocity theorem is used to derive the Fredholm integral equation and impedance increment formulas of probe coil in numerical calculation of eddy current nondestructive testing.更多还原
