Abstract: Recently proposed leapfrog complying-divergence implicit-finite-difference time-domain (CDI-FDTD) method features many advantages over other unconditionally stable FDTD methods, such as unconditional stability, complying-divergence, and efficient leapfrog scheme with reduced right-hand-side (RHS) flops.

DOI: 10.1109/tap.2025.3602126
Abstract: The conventional Yee grid modeling approach employed within the unconditionally stable complying-divergence implicit finite-difference time-domain (CDI-FDTD) technique commonly encounters substantial staircasing errors when simulating objects with curved perfect electric conductor (PEC) structures. In response to… read more here.

DOI: 10.3390/axioms11010023
Abstract: The leapfrog schemes have been developed for unconditionally stable alternating-direction implicit (ADI) finite-difference time-domain (FDTD) method, and recently the complying-divergence implicit (CDI) FDTD method. In this paper, the formulations from time-collocated to leapfrog fundamental schemes… read more here.
