An off-grid boundary condition within Yee's finite-difference time-domain (FDTD) is presented. The boundary fields are extrapolated from the internal computational domain using the Theory of Image. The method enhances the flexibility of the FDTD method with respect to complex geometrical domains in a uniform standard FDTD mesh, using the standard FDTD code.

Abstract
An off-grid boundary condition within Yee's finite-difference time-domain (FDTD) is presented. The boundary fields are extrapolated from the internal computational domain using the Theory of Image. The method enhances the flexibility of the FDTD method with respect to complex geometrical domains in a uniform standard FDTD mesh, using the standard FDTD code. Curved surfaces are introduced without reducing the time step and maintaining the stability of the simulation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
