Finite Difference Time Domain (FDTD) Characterization of a Single Mode Applicator
Journal of Microwave Power and Electromagnetic Energy, 2003Microwave heating plays an important role in the processing & heating of foods in the food industry and at home, but the applicator design is frequently an arduous task. Thefinite-difference time-domain (FDTD) method can be used to model complex geometries and guide the design of different types of applicators.

Finite-difference time-domain (FDTD) analysis using distributed computing
IEEE Microwave and Guided Wave Letters, 1994This paper describes an implementation of the finite-difference time-domain (FDTD) calculations using PVM [Parallel Virtual Machine] 3.2 and a cluster of workstations for a test problem involving a three-dimensional rectangular cavity. It is found that the speedup factors achieved in FDTD calculations can approach the maximum values for large problem ...

Accelerating the simulation of Finite Difference Time Domain (FDTD) with GPU
2021 IEEE International Joint EMC/SI/PI and EMC Europe Symposium, 2021In this paper, we discuss the implementation of three dimensional FDTD method to Nvidia’s CUDA architecture. Finite-difference time-domain is a numerical analysis technique used for modeling computational electrodynamics. Since it is a time-domain method, FDTD solutions can cover a wide frequency range with a single simulation run, and treat nonlinear ...

Conformal finite-different time-domain (FDTD) with overlapping grids
IEEE Transactions on Antennas and Propagation, 1992It is shown how to use many overlapping conformal grids in the neighborhood of the scatterer while using a rectangular grid away from the scatterer for solving Maxwell's equations. The locally conformal grids allow better approximation of the boundary condition on the scattering object while the rectangular grid preserves the simplicity and accuracy of

Conformal finite difference time domain (FDTD) with overlapping grids
IEEE Antennas and Propagation Society International Symposium 1992 Digest, 1992A conformal FDTD technique based on overlapping grids is proposed. Sample calculations show that this conformal FDTD is more accurate than the staircasing FDTD and that the bookkeeping seems to be less intensive than that of the locally distorted grid conformal FDTD. The authors have built 2-D and 3-D overlapping grid conformal FDTD codes and have done

A distributed implementation of the finite difference time‐domain (FDTD) method
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 1995AbstractThe finite difference time‐domain (FDTD) method is a well known numerical technique that has been used to solve electromagnetic boundary value problems. However, the method requires large computational resources to solve a problem, restricting its use on sequential computers to small problems.This has led to the use of expensive supercomputers ...
