摘要

The reduction of the total computational overheadin the design of complex geometries, such as modern aircrafts,is a very challenging problem, particularly when electrostaticfields (ESF) for lightning protection, are considered.To this aim, an efficient ESF evaluation scheme, based on thenonstandard finite-difference time-domain (NS-FDTD) method,is proposed. Combining the total-field/scattered-field (TF/SF) conceptwith a distinct sine-wave form, the novel technique cancelsthe accumulative errors caused by the static field component.Numerical results reveal that the featured method enables theuse of high-frequency discretization models to ESF proble
