This technique helps avoid local time-step restrictions caused by irregular cells, thereby im- proving the global stability criterion of the original Dey-Mittra method. The approach retains a second-order spatial convergence. A numerical experiment based on the NASA almond has been chosen to show the improvement in accuracy and computational performance of the proposed method.}, organization = {The work described in this letter and the research leading to these results has received support from the Projects TEC2013- 48414-C3-01 and TEC2015-68766-REDC (MINECO, Spain), P12-TIC-1442 (Junta de Andalucia, Spain), Alhambra-UGRFDTD (AIRBUS DS), and by the CSIRC alhambra.ugr.es supercomputing center.}, publisher = {IEEE}, keywords = {Conformal techniques}, keywords = {Finite-difference time domain}, keywords = {Radar cross-section}, title = {A New efficient and stable 3D Conformal FDTD}, doi = {10.1109/LMWC.2016.2588579}, author = {Ruiz Cabello, Miguel and Díaz Angulo, Luis Manuel and Alvarez Gonzalez, Jesús and Rubio Bretones, Amelia Consuelo and Gutierrez Gutierrez, Guadalupe and González García, Salvador}, }
