A Novel Single-Source Surface Integral Method to Compute Scattering from Dielectric Objects
Utkarsh R. Patel, Piero Triverio, Sean V. Hum
Using the traditional surface integral methods, the computation of scattering from a dielectric object requires two equivalent current densities on the boundary of the dielectric.…
A Stable FDTD Method with Embedded Reduced-Order Models
Xinyue Zhang, Fadime Bekmambetova, Piero Triverio
The computational efficiency of the Finite-Difference Time-Domain (FDTD) method can be significantly reduced by the presence of complex objects with fine features. Small geometrica…
A Dissipative Systems Theory for FDTD with Application to Stability Analysis and Subgridding
Fadime Bekmambetova, Xinyue Zhang, Piero Triverio
This paper establishes a far-reaching connection between the Finite-Difference Time-Domain method (FDTD) and the theory of dissipative systems. The FDTD equations for a rectangular…
