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...

Reducing the Setup Time of a One-Step FDTD Method

As society places greater demands on technology, it becomes increasingly important to be able to simulate that technology. While simulation tools can be very sophisticated and capable of handling very complex devices and structures, the cost paid in computation time can be prohibitive. To reduce this time, a number of one-step schemes have been developed, but these schemes suffer from a setup t...

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...

Scattered-Field FDTD and PSTD Algorithms with CPML Absorbing Boundary Conditions for Light Scattering by Aerosols

As fundamental parameters for polarized-radiative-transfer calculations, the single-scattering phase matrix of irregularly shaped aerosol particles must be accurately modeled. In this study, a scattered-field finite-difference time-domain (FDTD) model and a scattered-field pseudospectral time-domain (PSTD) model are developed for light scattering by arbitrarily shaped dielectric aerosols. The c...
