　　主题一：Recent Developments in Computational Electromagnetics using FDTD Method

　　主讲人：IEEE Fellow、科罗拉多矿业学院 Atef Z. Elsherbeni 教授

　　交流内容：

　　This presentation will focus on recent developments in the finite difference time domain (FDTD) method for electromagnetics and antenna applications. First a brief introduction to the method, its capabilities, and the type of lumped circuit elements, linear and non-linear, which can be integrated into an electromagnetic simulation will be presented. The speed up of the FDTD method using graphical processing gaming cards (GPUs) along with the use of different programming languages such as Fortnan, Matlab, CUDA, and OpenCL will be highlighted.

　　主　题二：New Development for DGTD Method and Its Applications

　　主讲人：江苏师范大学  Lei Zhao 副教授

　　交流内容：

　　A general numerical scheme is proposed for the waveport modeling and scattering-parameter (S-parameter) extraction of inhomogeneous waveports with the discontinuous Galerkin time-domain method. In this scheme, the waveports are truncated with perfectly matched layers with a hybrid mesh automatically extruded from the mesh of the physical device to be simulated. The waveports are then excited by a total-field/scattered-field technique, with which the incident and scattered waves can be obtained for an accurate calculation of the S-parameters. A novel eigenmode solver is also developed to calculate the required modal profiles for the eigenmodes in both homogeneous and inhomogeneous waveports. Special attention is paid to the S-parameter extraction for evanescent modes, which has been a difficult task for time-domain simulations. Numerical examples are given to validate the proposed numerical scheme.
