The transmission simulator method of experimental dynamic substructuring captures the interface forces and motions through a fixture called a transmission simulator. The transmission simulator method avoids the need to measure connection point rotations and enriches the modal basis of the substructure model. The free modes of the experimental substructure mounted to the transmission simulator a...

The microstrip line is widely used as the planar transmission line in microwave integrated circuits and high speed interconnecting buses. In this paper, we use COMSOL multiphysics to study multiconductor microstrip systems on microwave integrated circuits. We specifically illustrate the modeling of open four and five conductors systems. We successfully demonstrated the calculation of the capaci...

the paper presents simulation results for the propagation of lightning surges along a transmission line and the overvoltages generated in a transformer at the end of the line. it is shown that the monte carlo simulation method provides more realistic assessments than the deterministic methods. it has also been shown that increasing capacitance in transformers results in reduced levels of overvo...

This thesis examines the effects of electromagnetic interference (EMI) and coupling in circuits and systems. The coupling phenomenon is investigated in nonuniform transmission lines and adjacent via structures in microelectronic circuits. Radiation from metallic enclosures with apertures and lined with resistive materials is analyzed. Electromagnetic interference on a larger scale is studied in...

In this study, electric field distribution analyses for three pylon models are carried out by a Finite Element Method (FEM) based software. Analyses are performed in both stationary and time domains to observe instantaneous values along with the effective ones. Considering the results of the study, different line geometries is considerably affecting the magnitude and distribution of electric fi...

Transmission line is a basic component in all passive devices, integrated circuits, and systems. Microstrip is the most popular transmission line in the microwave and millimeter-wave frequencies, and has been widely used in current electronic devices, circuits, and systems. One of the important issues to be solved in such applications is the relatively large transmission loss of microstrip. Her...

A subgridding formulation of Agrawal coupling equations of transmission line with branch and distributed electromagnetic excitation is proposed. This algorithm enables us to solve the transmission line system using different temporal and spatial step on different branches. The method is used to calculate the lightning induced over-voltage on the transmission line installed with air gap componen...
