A Novel Efficient WLP-Based BOR FDTD Method With Explicit Treating Ideology

BOR-FDTD subgridding based on finite element principles

In this paper a recently developed provably passive and stable 3D FDTD subgridding technique, based on finite elements principles, is extended to Body-Of-Revolution (BOR) FDTD. First, a suitable choice of basis functions is presented together with the mechanism to assemble them into an overall mesh consisting of coarse and fine mesh cells. Invoking appropriate masslumping concepts then leads to...

BOR-FDTD Analysis of Spherical Lens Multi-beam Antenna

The multi-beam antenna system has important applications in the aeronautics and astronautics field, which has caught much attention in recent years. This paper analyze a multibeam antenna consisted of spherical lens and multi feeds. Firstly, the single feed’s performance of the spherical-lens antenna is analyzed. In view of the axial symmetry of the antenna, the BOR-FDTD method is used to reduc...

An Efficient Implementation of Phase Field Method with Explicit Time Integration

The phase field method integrates the Griffith theory and damage mechanics approach to predict crack initiation, propagation, and branching within one framework. No crack tracking topology is needed, and complex crack shapes can be captures without user intervention. In this paper, a detailed description of how the phase field method is implemented with explicit dynamics into LS-DYNA is provide...
