Wave Concept Iterative Process Merges with Modal Fast Fourier Transformation to Analyze Microstrip Filters.

Abstract

A novel iterative method based on the concept of waves is reported for use in the field theory, computer aided design and optimization of high frequency integrated circuits. It consists of a recursive relationship between a given source and reflected waves from the discontinuity plane which is divided into cells. A high computational speed has been achieved by using Modal Fast Fourier Transformation (MFFT). The theory as well as its procedure implementation is described. Numerical results are succussfully compared with published data.
