Description

In previous research a mode matching approach was used to describe the electromagnetic properties of a system formed by an open-ended waveguide and a crack [1]. A more versatile formulation for evaluating the electromagnetic properties in such a system is possible by using a moment solution approach, which eliminates the necessary distinction between empty, filled and finite length cracks, independent of the relative position of the crack within the probing waveguide aperture. The reflection coefficient at the waveguide aperture can be expressed with a generalized scattering matrix, thus making this approach versatile for any incident excitation field [2].
