CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishAn 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.
