Finite-difference analysis of open and short circuits in coplanar MMICs including finite metallization thickness and mode conversion

Open and short circuits as used in MMICs (monolithic microwave integrated circuits) are investigated by means of a finite difference method in the frequency domain. Both mode conversion and finite metallization thickness are accounted for. For the open stub, noticeable mode conversion is observed, whereas the short circuit behavior shows a significant dependence on metallization thickness.<<ETX>>
