Abstract:

A generalized three-dimensional computational numerical code is developed for Monolithic Microwave Integrated Circuit (MMIC) structures based on a full wave approach using integral equation techniques. The electromagnetic properties of the MMIC structures are calculated using a Method of Moments - Galerkin technique based on integral equations and the relevant Green function to obtain a rigorous formulation. The MMIC structures are assumed to have an arbitrary geometry involving orthogonal parallelepiped 'cells', each one of which is characterized with finite permittivity and conductivity values. A novel approach is proposed to treat the incident: reflected and transmitted waves at the two microstrip lines, which stand as input and output of the circuit. Their current distribution is also being taken into account in terms of incident, reflected and transferred waves. The derived matrix is being inverted and the obtained results are the unknown coefficients of the plane waves inside the 'cells' and also the reflection R and transfer T coefficients. The derived numerical results concern linear cases, while the examination of non-linear structures have been taken into account in the analytical formulation.
