In this paper we present two simulation techniques for modeling periodic structures with three-dimensional elements in general. The first of these is based on the Method of Moments (MoM) and is suitable for thin-wire structures, which could be either PEC or plasmonic, e.g., nanowires at optical wavelengths. The second is a Finite Difference Time Domain (FDTD)-based approach, which is well suited for...
Two-dimensional periodic structures, that exhibit spatial filtering characteristics, find a variety of applications in defense as well as communication. Several PBC/FDTD schemes have been proposed for analyzing such structures. By incorporating the PBC, which takes advantage of the periodicity inherent in the geometry as well as the excitation, the simulation of the original problem is reduced to...
In this paper we study the antenna/woodpile electronic bandgap (EBG) composite by using the finite difference time domain (FDTD) Method. The near-field as well as far-field performance are examined at different frequencies with a view to realizing enhanced directivity. In addition, the structure is modeled and simulated under plane wave illumination and the scattered fields are computed to gain an...
