ABSTRACT
In this paper, we introduce TeraFoils, a method for designing and fabricating material-based structures using binary holograms in the terahertz region. We outline the design, fabrication, imaging, and data processing steps for embedding information inside physical objects and exploring a method to create holographic structures with silver-foiled paper. This paper is a sheet on which silver foil is pasted where the ink is printed, using a home-use laser printer and an electric iron. Wave propagation calculations were performed to design a binary-amplitude hologram. Along with the designed pattern, we fabricated silver-foiled binary holograms in the sub-terahertz range (0.1 THz) and confirmed their functions using a two-dimensional THz sensor.
