000013555 520__ $$2eng$$aThe present work is devoted to a theoretical analysis and numerical modeling of the phenomena of high-frequency wave propagation in honeycomb-type periodic media. A onedimensional periodic elastic rod model and a two-dimensional periodic elastic beam hexagonal model are considered. The Bloch wave direct and inverse transformations are applied to find general or particular solutions. By identifying eigenfrequencies and the corresponding eigenmodes of the periodic systems, important information, such as the frequency bandgaps and the diffracted waves caused by the periodic cells, is obtained. The aims are to improve our understanding of how HF waves are transmitted and attenuated in the studied periodic media and to link the theoretical analyses to our numerical assessments.
