On the convergence and accuracy of the FDTD method for nanoplasmonics
Use of the Finite-Difference Time-Domain (FDTD) method to model nanoplasmonic structures continues to rise - more than 2700 papers have been published in 2014 on FDTD simulations of surface plasmons. However, a comprehensive study on the convergence and accuracy of the method for nanoplasmonic structures has yet to be reported.

A linear bicharacteristic FDTD method [PDF]
The linear bicharacteristic scheme (LBS) is a classical leapfrog algorithm, but is combined with upwind bias in the spatial derivatives. This approach preserves the time-reversibility of the leapfrog algorithm, which results in no dissipation, and it permits more flexibility by the ability to adopt a characteristic based method.

In this paper, we proposed a novel multilayer perceptron (MLP) based Finite-Difference Time-Domain (FDTD) method to reduce the time complexity of the conventional FDTD method, MLP neural networks can be used to replace the field quantities update equations and we found that in certain scenario, we can greatly reduce the time complexity of FDTD method.
