Computational Electromagnetic Study of Reduction of Skin-Effect Losses by Using Laminated Conductors

During recent years, technology to respond the high demand for high-speed data transmission has developed rapidly. It is important to realize that with high speed data transmitted, the signal integrity is worrisome. The term “skin effect” was introduced as it varies with the frequency used to transmit high-speed data. At higher frequency, skin-effect losses are greater, leading to less accurate received data. Reduction of the skin-effect losses in a transmission line has been found to improve the accuracy of transmitted data. One of the possible ways to achieve this is to properly design the transmission line using the model of laminated conductors separated by sheets of insulators, which is the subject of this thesis. The model consists of sheets of copper separated by sheets of glass. To see how the laminated conductor model works, a solid conductor is generated, and both models are simulated in the program called ANSYS Q3D-2D Extractor in order to compare the results with the theoretical calculation. By generating the model with varying dimensions and thickness, the results vary interestingly with the number of layers and the size of the models. The laminated conductor has less skin effect than a solid conductor when the frequency of data transmission is high, and the skin effect tends to be much less at higher frequency.U of I OnlySenior thesis not recommended for open acces
