ScholarBank@NUS Repository. https://doi.org/10.1109/APS.2011.5996988 | Abstract: | A discontinuous Galerkin time-domain finite-element method (DG-TDFEM) is developed for modeling wideband EM response of dielectric loaded waveguide structures. It can be considered as a kind of domain decomposition method (DDM). The hierarchical vector basis functions are used to expand the electric and magnetic fields to maintain high order accuracy and Crank-Nicolson (CN) difference scheme is utilized for the time-partial equation for each subdomain. The fields in adjacent subdomains are directly related to each other by the fields on their interfaces. Thus, there is no need to solve a global matrix equation related to all boundary values. The complex frequency-shifted perfectly matched layers (CFS-PML) are used for the truncation of solution domain. 3-dimensional cavity and waveguide structure with dielectric loading are simulated to demonstrate the accuracy and efficiency of the proposed method. © 2011 IEEE. | Source Title: | IEEE Antennas and Propagation Society, AP-S International Symposium (Digest) | URI: | http://scholarbank.nus.edu.sg/handle/10635/117242 | ISBN: | 9781424495634 | ISSN: | 15223965 | DOI: | 10.1109/APS.2011.5996988 |
