Abstract :
For longitudinal slots cut in rectangular waveguides, the longitudinal component of the aperture electric field is found to be significant when the offset is small even for narrow slots. Ignoring the E-longitudinal component can introduce substantial error in the computed scattering parameters for weakly excited slots.
