WebFDTD Finite-difference time-domain (FDTD) is a method for solving Maxwell’s Equations, which describe classical Electrodynamics. It is a general method that can give both the full time dynamics of the electromagnetic fields or the steady state behavior. WebAug 19, 2024 · Finite difference time domain (FDTD) simulations are performed to optimize the positions of the gaps in the shield for a flat current profile. Lumped inductors are added to each end to reduce losses. The performance of a single antenna is compared to a fractionated dipole using B 1 maps and MR thermometry.
