For any

square integrable function x on [-1, 1], we define the function

Equation (2) means that the only a priori information about the magnetic current is that it is a square integrable function defined on the source domain S whereas the radiated field is assumed as a square integrable function defined on the measurement domain [O.

that relates the square integrable function electric current J(x') defined on the source domain S to the radiated electric field over the measurement domain [O.
