Time domain analysis lines Ahmad Chaldavi*, Homayoon Oralzi* and Mahmoud Kamarel** *Iran University of Science and Technology, Tehran, Iran. **Tehran University, Tehran, Iran. 1 Abstract A simple numerical method is developed for the determination of the transient response of lossy transmission lines with a general impedance loading to a general voltage excitation. First, the transient response of

Field theory design of a novel circular waveguide dual-mode filter S Moretti, F Alessandri, R Sorrentino Istituto di Elettronica, University of Perugia, 06125 Perugia, Italy 1 Abstract A novel and simple configuration is proposed for the realization of dual-mode filters. The geometry consists of a circular cavity coupled with rotated rectangular waveguides through thick irises, with no need of tu
