Abstract

Abstract Objective: This project seeks to formulate a clear and consistent interpretation of optical dynamics so that field interactions with matter can be confidently modeled in a manner previously impossible. Such will enable educators to teach modern electrodynamics with confidence and allow for the development of applications involving electromagnetic fields. In pursuit of this goal, the specific aim of the proposed project is to answer, within the framework of classical electrodynamics, the questions ?how do we express with confidence the dynamics of complex material systems subject to optical/electromagnetic forces?? and ?how are the various models of electromagnetic forces and momentum interrelated?? This new interpretation will be applied to evaluate emerging and proposed technologies. Intellectual Merit: This research will provide the background necessary for modeling complex systems where electromagnetic fields are used for self-assembly and in situ control of photonic structures and will additionally benefit biology and medicine where optical forces are currently used to probe the mechanical properties of living cells. Applications focus on efficient and sustainable use of resources and include the use of optical matter for fabricating nanophotonic structures for various applications. Broader Impacts: This grant will assist in advancing technology developments in Arkansas through a collaborative effort with other grants and contracts to build regional centers of excellence, which will promote new innovation while encouraging small business development. This work also proposes to improve how engineering education treats field interactions with matter, an approach that will have a fundamental impact on the preparedness of next generation engineers.
