A conformal FDTD algorithm for modeling perfectly conducting objects with curve-shaped surfaces and edges

High-order conformal symplectic FDTD scheme

“…3, compared with the LC-FDTD(2,2) method and the HS-SFDTD(3,4) approach, the HC-SFDTD(3,4) scheme agrees with the Mie series solution very well. The relative two-norm errors of the bistatic RCS in H-plane for the LC-FDTD(2,2) method, the HS-SFDTD (3,4) approach, and the HC-SFDTD(3,4) scheme are, respectively, 7.3%, 12.1%, and 0.83%. Figure 3 Within the same relative two-norm errors bound (1%), we change the settings of the space step and the CFL number, and the CPU time and memory consumed by different algorithms are recorded in Table I.…”

Optimized Simulation Algorithms for Fractal Generation and Analysis

“…For fractals, complex adaptive mesh refinement (AMR) techniques may be required [18]. A simpler approach which accurately models PEC surfaces without sub-gridding makes use of conformal finite-difference time-domain (CFDTD) algorithms with locally-conformal grids [19].…”
