Abstract

"Monitoring and maintaining civil, space, and aerospace infrastructure is an ongoing critical problem facing our nation. As new complex materials and structures, such as multilayer composites and inflatable habitats, become ubiquitous, performing inspection of their structural integrity becomes even more challenging. Thus, novel nondestructive testing (NDT) methods are needed. Chipless RFID is a relatively new technology that has the potential to address these needs. Chipless RFID tags have the advantage of being wireless and passive, meaning that they do not require a power source or an electronic chip. They can also be used in a variety of sensing applications including monitoring temperature, strain, moisture, and permittivity. However, these tags have yet to be used as embedded sensors. By embedding chipless RFID tags in materials, materials characterization can be performed via multi-bit sensing; that is, looking at how the multi-bit code assigned to the response of the tag changes as a function of material. This thesis develops this method through both simulation and measurement. In doing so, a new coding method and tag design are developed to better support this technique. Furthermore, inkjet-printing is explored as a manufacturing method for these tags and various measurement methods for tags including radar cross-section and microwave thermography are explored"--Abstract, page iii.
