Berdasarkan algoritma genetik (GA) dalam makalah ini, kami membentangkan kaedah mudah untuk mengekstrak parameter litar teragih bagi berbilang talian penghantaran mikrojalur tidak seragam yang digabungkan daripadanya yang diukur atau dikira. S-parameter. Talian mungkin tidak hilang atau hilang, dengan parameter bergantung kepada frekuensi. Pertama, jumlah maklumat yang mencukupi tentang sistem diukur atau dikira pada julat frekuensi tertentu. Kemudian maklumat ini digunakan sebagai input untuk GA untuk menentukan matriks kearuhan dan kemuatan sistem. Teori yang digunakan untuk penilaian kecergasan adalah berdasarkan penghampiran garis langkah bagi talian penghantaran tidak seragam dan andaian kuasi-TEM. Menggunakan penghampiran garis langkah, sistem talian penghantaran tidak seragam berganding dibahagikan kepada sebilangan besar talian seragam berganding (garisan langkah) dengan ciri yang berbeza. Kemudian dengan menggunakan kaedah penguraian modal, sistem persamaan pembezaan separa berganding untuk setiap langkah diuraikan kepada beberapa persamaan gelombang biasa tidak berganding yang kemudiannya diselesaikan dalam domain frekuensi.

Abstract: Based on genetic algorithm (GA) in this paper we present a simple method to extract distributed circuit parameters of a multiple coupled nonuniform microstrip transmission lines from it's measured or computed S-parameters. The lines may be lossless or lossy, with frequency dependent parameters. First a sufficient amount of information about the system is measured or computed over an specified frequency range. Then this information is used as an input for a GA to determine the inductance and capacitance matrices of the system. The theory used for fitness evaluation is based on the steplines approximation of the nonuniform transmission lines and quasi-TEM assumptions. Using steplines approximation the system of coupled nonuniform transmission lines is subdivided into arbitrary large number of coupled uniform lines (steplines) with different characteristics. Then using modal decomposition method the system of coupled partial differential equations for each step is decomposed to a number of uncoupled ordinary wave equations which are then solved in frequency-domain.
