Abstract :
Theorems of Fourier transform cannot be applied to prove that evanescent waves do not contribute into the power passed through the initial plane because the Fourier spectrum of the boundary value is by the most part singular. Their contribution is considered in details in the case of linear source. It is shown that evanescent waves transfer the power in both directions and do not contribute into the total passed power.
