ABSTRACTThe transfer matrix method (TMM) software (Translight, A. Reynolds [I]) was used to evaluate the photonic band gap (PBG) properties of the periodic arrangement of high permittivity ferroelectric composite (40 wt% Ba 0 . 45 Sr 0 . 55 TiO 3 /60 wt% MgO composite, ER = 80, tan8 = 0.0041 at 10 GHz) in air (or Styrofoam, FR -1) matrix compared to a lower permittivity material (A1 2 0 3 , CR = 11.54, tan8 = 0.00003 at 10 GHz) in air. The periodic structures investigated included a one-dimensional (ID) stack…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
