PIERS2018 Toyama Focus/Special Sessions

SC1: Recent Approaches to Periodic Structures 1

Organized by Prof. Koki Watanabe (Fukuoka Institute of Technology) and Prof. Gerard Granet (Universite Clermont Auvergne)

Session's Information:

Periodic structures have been widely used as wavelength and polarization selective components in microwave, millimeter-wave, and optical wave regions, because combination of ordered objects and their order induces irreplaceable properties of the EM wave propagation. In addition, small collapses in periodic structures are sometimes useful to control EM wave propagation in periodic structures, and imperfectly periodic structures received much interest. Consequently, analytical and numerical approaches to the EM fields in the perfectly/imperfectly periodic structures have been extensively studied for a long time. Numerical error is comparatively easy to accumulate in the structures, and careful treatments of boundary conditions are necessary in many problems. Furthermore, recently developed applications often use the evanescent wave and/or the polarimetric information, and require highly accurate numerical modeling in many cases. This session will cover recent progress in the analytical and numerical approaches to EM fields in the perfectly/imperfectly periodic structures, such as diffraction gratings, electromagnetic bandgap structures, metamaterials, frequency selective surfaces, reflect arrays, and related areas.
