本文提出了一种用于太赫兹频段数据编码的无芯片、低成本标签的新结构。该器件基于多层结构，其中不同层的厚度是波长的量级，即在亚毫米范围内。在这种设备中，由于折射率可调和低成本材料，信息被编码在标签的体积中，从而实现了高级别的安全性。例如，与经典的射频识别标签相比的两个主要优点是不存在金属和将信息编码在结构的体积中，从而限制了在处理过程中的损坏风险并防止了反向工程。
In the present paper, we propose a new structure of chipless and low-cost tag for data encoding in the terahertz frequency range. The device is based on a multilayer structure in which the thicknesses of the different layers are of the order of the wavelength, i.e., in the submillimeter range. In this device, the information is encoded in the volume of the tag thanks to the adjustable refractive index and low-cost materials, leading to a high level of security. The two main advantages compared to classical radiofrequency identification tags are the absence of metal and the encoding of the information in the volume of the structure, thus limiting the risk of damage during handling and preventing from reverse engineering, for example.
