One of the antireflection technologies is known as the moth-eye structure, which is a periodic array of pyramid-shaped structures. Moth-eye structures for terahertz band antireflection are mainly fabricated by ultrashort pulsed laser processing, and most of them are square lattices. In this study, we fabricated moth-eye structures with different lattices by laser processing and showed that the structure with a hexagonal lattice has the broadest bandwidth antireflection properties.
