In this study. we present an investigation of the optical properties and band structures for the conventional and Fibonacci photonic crystals (PCs) based on some A5B6C7 ferroelectrics (SbSBr and BiTeCl). Here. we use one dimensional SbSBr and BiTeCl based layers in air background. https://www.markbroyard.com/top-super-pet-naturals-busy-butter-calming-peanut-butter-for-cheap-limited-save/
