Abstract: We present a rigorous theory for oblique incident Hermite-Gaussian beams, diffracted by two slits of width ? and separation d, in a thick metallic screen for the case of polarization TM(S). The far field spectra as a function of several opto-geometrical parameters, wavelength ?, slit width ?, separation d, incidence angle ?_i and Hermite order m is analyzed. In the vectorial diffraction region given when ?/? >0.2, where ? is the incident wavelength and as a function of the separation between slits d, we have numerically analyzed: the far field spectra, the energy diffracted along the incident beam direction (E_i ), and the validity of an approximate diffraction (scalar) property, namely E_i= Nt/?.
