| dc.description.abstract | Numerical methods are very important in the areas of microwave and RF engineering, antenna design, bio-electromagnetics, electromagnetic compatibility and interference (EMC/EMI). Among several techniques, time domain methods such as the Finite Difference Time Domain (FDTD) method and the Transmission Line Matrix (TLM) method are of particular interest, due to their high flexibility and ease of implementation, given the powerful computation resource available. This dissertation is focused on the TLM method, a discrete time evolution scheme, based on the analogy between the discretized electromagnetic field and a mesh of transmission lines. Generally, in a numerical method, much effort is spent on reducing the computational burden, increasing the ability and flexibility to handle hybrid problems and to model various properties of materials. The objective of the proposed research is to a) develop, implement, and test several techniques aimed at enhancing the accuracy of time domain analysis of microwave and high speed circuits without increasing the computational load, b) to develop methods to embed circuits and devices into a field environment or to import field analysis into a circuit simulator, and c) enhance the modeling of a wide range of materials, including metamaterials with negative refractive index, and magnetized ferrites. By making good use of these techniques it is possible to incorporate more information into the TLM solution, thus enabling more accurate, more efficient and more powerful CAD tools for industry and academia. | en |
