Full-Vectorial Meshfree Finite Cloud Mode Solver for Fused Fiber-Optic Couplers

A novel full-vectorial meshfree finite cloud mode solver is proposed for analysis of fused optic-fiber couplers, in which the curvilinear coordinate mapping technique is used to map a cloud with curved interface onto a unit square. Numerical results are compared with prior analysis using the finite difference method, showing the validity and utility of the proposed method.
