Time-Domain Algorithms for Computational Electromagnetics

Locally implicit discontinuous Galerkin method for time domain electromagnetics

In the recent years, there has been an increasing interest in discontinuous Galerkin time domain (DGTD) methods for the solution of the unsteady Maxwell equations modeling electromagnetic wave propagation. One of the main features of DGTD methods is their ability to deal with unstructured meshes which are particularly well suited to the discretization of the geometrical details and heterogeneou...

Modelling and application: A research domain in mathematics education

Abstract: The main purpose of this paper is introducing modelling and application as a research domain in mathematics education through reviewing related literature. The first purpose of this review is to give a more clear meaning of modelling and application, and base on that, makes the distinction between modelling in mathematics education & modelling in other scientific domains. There are so...

Time-domain Integral-equation-based Solver for Transient and Broadband Problems in Electromagnetics

A time-domain (TD) numerical method has been developed based on the method-of moments (MoM) and marching-on-time (MoT) solution of the electrical-type integral equation with mixed potential formulation and free-space Green’s functions. This timedomain integral-equation (TDIE) code is applicable for arbitrary 3-D antennas and arrays composed conductors. It was developed particularly to simulate ...

Multi-Region Finite Difference Time Domain Simulation for Airborne Radar

Traditional finite difference time domain (FDTD) is classic numerical method for solving wave propagation problems such as electromagnetic wave, seismic wave and acoustic wave. As for airborne GPR simulation, modeling space is so large that memory consuming is pretty huge; on the other hand, the area between source antenna and ground surface is homogenous medium – air, where analytic solution c...
