Electromagnetic time domain modeling using an improved meshless method

Summary form only given, as follows. In this paper, a modified meshless method is extended to time-domain electromagnetic modeling. The time derivatives are still tackled with the customary explicit leapfrog time scheme. In the space domain, the fields at the collocation points are expanded into a series of new Shepard functions and are treated with a meshless method procedure. In comparison with the traditional schemes of the meshless methods, this approximation function has lower computational cost with same level of accuracy.
