Abstract

Memristor is a new nonlinear circuit element. Examination of its use with other circuit elements is important from Circuit analysis point of view. A memristor connected at the end of a transmission line will exhibit a different behavior than a resistor does. It is difficult or impossible to solve such a problem since the memristor is a nonlinear circuit element. In this study, the equation of the electromagnetic wave propagating over the transmission line with a memristor load is solved using the finite-difference time-domain (FDTM) method. Memristor current and voltage are calculated depending on time. The simulations are made with the MATLAB program.

Keywords

Bir İletim Hattından Beslenen Bir Memristörün Zamanda Sonlu Farklar Yöntemi İle Çözümü

Abstract

Memristör yeni bir doğrusal olmayan devre elemanıdır. Diğer devre elemanları ile birlikte kullanımın incelenmesi Devre analizi açısından önemlidir. Bir iletim hattının sonuna bağlanan memristör elemanı bir dirence göre daha farklı bir davranış sergileyecektir. Memristor nonlineer bir devre elemanı olduğu için, böyle bir problemin çözümünün yapılması zor ya da imkansızdır. Bu çalışmada, bir memristor ile yüklü bir iletim hattının üzerinde yayılan elektromanyetik dalganın denklemi Zaman Domeninde Sonlu Farklar (ZDSF) yöntemi kullanılarak çözülmüştür. Memristör akımı ve gerilimi zamana bağlı olarak hesaplanmıştır. Simülasyonlar MATLAB programı ile yapılmıştır.
