ECE Undergraduate student Hollyn Benson and ECE Graduate student Dustin Pieper will be involved in this interdisciplinary project. Mr. Pieper will be responsible for designing a Frequency Selective Surface (FSS) element, optimized for characterization of shear strain. He will also study the possibilities of applying this FSS approach without the inclusion of ground plane. Ms. Benson will be responsible for conducting any required literature search (under the direction of PI Donnell, assisted by Mr. Pieper) and conducting electromagnetic simulations using the FSS model developed by Mr. Pieper.
|The objective of this project is to design an embedded integrated sensor capable of characterizing mechanical properties including shear strain for inspection of composite structures (i.e., structural health monitoring). This sensor will be designed using a Frequency Selective Surface (FSS) approach. To this end, the FSS element must be carefully designed such that its electromagnetic response is optimized for characterization of shear strain. This design will include a study on the effect of a ground plane, and will also study the possibility of using an FSS element without a ground plane.
|The objective of this project is to design an embedded sensor element capable of characterizing mechanical properties including shear strain. This element will be designed using a Frequency Selective Surface (FSS) approach, and will be intended for integration into composite materials. The successful outcome of this project will result in a new embedded integrated sensing method with the potential to significantly impact the method by which composite structures are inspected. Further, the outcomes of this project may directly impact the potential for remote (standoff) inspection of such structures.
Relationship to other Research/Projects
This project focuses on the application of FSS to the development of an integrated embedded sensor capable of measuring shear strain. This application of FSS sensor development is relatively new, and very little work has been done in this area, in particular focusing on shear strain characterization. This project will allow PI Donnell and Co-PI Kinzel to build upon their experience with FSS (Kinzel) and antenna design, fabrication, and test (Donnell), providing a new avenue of collaborative interdisciplinary research. The result of this new collaborative research direction will be a novel sensor design with immense potential for structural health monitoring of composite materials and structures.

Technology Transfer Activities
|At the conclusion of this project, a journal paper will be submitted to a suitable, peer-reviewed publication. A final report summarizing the findings of this research will be submitted at the completion of the project. A short article will be submitted for the CTIS newsletter if requested and a presentation will be given at the Missouri S&T Transportation Infrastructure Conference, should this project be selected for the program.

It is expected that at the conclusion of this project, a new embedded integrated sensing method employing FSS principles will be developed. This novel method may have the potential to change the methodology used for composite structures inspection. Further, the outcomes of this project may directly impact the potential for remote (standoff) inspection of such structures.
