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...

متن کاملSubgridding Scheme for FDTD in Cylindrical Coordinates
A grid resolution compensation scheme based on subgridding is proposed and evaluated for improving the performance of the finite-difference time-domain method implemented in cylindrical coordinates. The scheme introduces subgrids into the domain with smaller azimuthal grid spacings. This work investigates interpolation methods used for estimating unknown but required field values at the interfa...
متن کاملExtension of the FDTD Huygens subgridding to frequency dependent media
A wide range of wireless system developments require knowledge of the distribution of electromagnetic fields from various sources in humans. As experimental assessment is ethically unacceptable, high resolution numerical dosimetry is needed. The FiniteDifference Time-Domain method is the most appropriate due to its simplicity and versatility. Reduction in demands on computational resources can ...
متن کاملBOR-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...
