Pereda, José A Grande Sáez, Ana María 2018-12-21T10:01:43Z 2018-12-21T10:01:43Z 2018 IEEE Microwave and Wireless Components Letters, 2018, Volume 28 , Issue 6, pp. 461-463 1531-1309 http://uvadoc.uva.es/handle/10324/33612 10.1109/LMWC.2018.2832014 The electric field computed by the locally 1-D finite-difference time-domain (FDTD) method at dielectric interfaces is investigated. To this end, two comprehensive problems are considered, namely a dielectric step in a rectangular waveguide and a dielectric-loaded metallic cavity. We found that, in both problems, the electric field patterns exhibit an unexpected phase shift at the dielectric interface. By contrast, the alternating-direction implicit FDTD method does not present this unphysical behavior. eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ © 2018 IEEE Attribution-NonCommercial-NoDerivatives 4.0 International On the Behavior of the LOD-FDTD Method at Dielectric Interfaces info:eu-repo/semantics/article
