DOI: 10.1016/j.cjph.2017.10.008
Abstract: Abstract Using the transfer matrix method approach (TMM), the microwave transmission spectra in hybrid quasi-periodic multilayer photonic structures are studied. These structures are formed by concatenating several quasi-periodic sequences such as the generalized Cantor (GC… read more here.
