The transfinite element method for modeling MMIC devices

A numerical procedure called the transfinite-element method is used in conjunction with the planar waveguide model to analyze monolithic microwave integrated circuit (MMIC) devices. By using analytic basis functions together with finite-element approximation functions in a variational technique, the transfinite-element method can be used to determine the fields and scattering parameters for a wide variety of stripline and microstrip devices.<
