Abstract :
Plane-wave scattering from an impedance rectangular pit by means of variational method is investigated. The problem is reduced to Fredholm´s integral equations with respect to finite functions. These functions are linear combinations of the tangential components of electrical and magnetic fields on the pit aperture. It is shown that the scattered far-field pattern is a stationary functional with respect to the finite functions. Numerical results of the problem solution are presented
