Abstract

This paper presents a novel split-field radial point interpolation meshless (RPIM) scheme for the study of periodic structures under oblique incidence condition. The time delay in the transverse plane is eliminated with the introduction of a set of auxiliary variables. With the application of split-field technique to the standard RPIM method, a leap-frog formulation is derived. Numerical experiment is implemented to demonstrate the effectiveness of the code and the obtained result is compared with result of split-field finite-difference time domain method.
