Abstract :
We derive an analytical expression for the coupling impedance and loss factor of a long narrow slot in a coaxial beam pipe. The method used differs from the classical Bethe´s theory of diffraction since we define differential polarizabilities to take into account the effect of the interference between the fields scattered all along the slot. The expressions obtained are thus valid even for slots longer than the wavelength
