Abstract
A microwave applicator device for the treatment of sheet or lap products comprising a housing defining a parallelepipedal waveguide cavity with dimensions a.times.b.times.L in an orthogonal coordinate system Ox, Oy, Oz, the housing being aligned along Oz and provided with slots for passing the product to be treated into the cavity along a plane parallel to the Ox, Oz plane, and means a microwave generator for exciting the cavity in Transverse Electric Mode, in order to create an electric field (E) internal to the cavity along a direction substantially parallel to Ox. The housing is such that the dimension a of the cavity is greater than a value substantially equal to the dimension b of the cavity.
