Automated network synthesis utilizing MAPLE

In microwave electromagnetic EM analysis, only a small part of the network needs to be modeled in details. The remaining part of the network can be reduced to an equivalent model. Two different approaches were commonly utilized to generate this model, namely, the time-domain and frequency-domain. The time-domain methods represent the system by a set of differential equations that are integrated to represent the system response. This method is accurate but at the expense of being computationally demanding. The frequency dependant network equivalent can be obtained either directly by direct methods or iteratively by using optimization techniques. This paper utilizes the frequency-domain approach to determine the most possible accurate equivalent configuration for the desired microwave filter. Moreover, the paper presents an automated procedure utilizing MAPLE to the generation of the circuit parameters that is capable on synthesizing low-pass, high-pass as well as band-pass filters.
