Characterization of a Coplanar Waveguide Open Stub-Based Discontinuity for MMICs and Filter Applications

<table>Boundary conditions enforced for application of FIT. A perfect magnetic conductor (PMC) was assumed on the side walls where the input and output ports intersect the feeding CPW (marked by blue ground symbols); perfect electrically conducting (PEC) walls were assumed on the top and bottom faces (marked by green ground symbols). </table>
