Diakoptic theory and the complex images for microwave integrated circuits

This paper presents an approach for rapid computation of microwave integrated circuit. The scheme includes the integral equation, a rapidly convergent Green's function by complex images, a multi-pipe method for large segments, and the diakoptic moment method. The scheme reduces the solution time of a two-stager MMIC amplifier of 411 segments to 3 minutes per frequency on a 33MHZ 80386 personal computer.
