项目摘要

This research seeks advancement of the basic knowledge of the physics of dusty plasmas (one of the fast growing areas of plasma physics), and its application to diverse environments such as the Earth's ionosphere, and laboratory and industrial plasmas. Areas of study include: (1) waves and instabilities in weakly coupled dusty plasmas, including effects such as magnetic fields, plasma inhomogeneities and boundaries, with detailed applications to dusty plasmas in the Earth's ionosphere and in the laboratory; (2) waves and structures in strongly coupled dusty plasmas, including waves in bilayers, and lattice structures of paramagnetic dust.(3) innovative applications involving interaction with electromagnetic waves. The proposal covers a broad range in that it investigates the basic physics of various dusty plasma environments, including space and laboratory dusty plasmas in magnetic fields, strongly coupled dusty plasmas, dust in microplasmas, and possible technological applications of dusty plasmas. The research includes training of students and broad dissemination of results through talks and publications. In addition, the research may have impacts on plasma technologies (e.g., plasma processing, nuclear fusion) in which dusty plasma concepts can play a role. Furthermore, some of the research may have overlap with topical research areas in photonics technology (e.g. photonic crystals).This proposal was submitted to the NSF-DoE Partnership in Plasma Science and Engineering joint solicitation 08-589. This award is being funded by the Plasma Physics Program in the Division of Physics.

这项研究寻求促进灰尘等离子体物理学的基本知识（等离子体物理学的快速生长领域之一），以及它在地球电离层，实验室和工业等离子等各种环境中的应用。研究领域包括：（1）弱耦合的灰尘等离子体中的波和不稳定性，包括磁场，等离子体不均匀性和边界等效果，以及在地球电离层和实验室中的尘土飞扬等离子体上的详细应用；（2）强烈耦合的灰尘等离子体中的波和结构，包括双层中的波和顺磁性灰尘的晶格结构。（3）涉及与电磁波相互作用的创新应用。该提案涵盖了广泛的范围，因为它研究了各种尘土飞扬的血浆环境的基本物理，包括磁场中的空间和实验室尘土飞扬的等离子体，强烈耦合的灰尘等离子体，微型粉尘中的灰尘以及可能的技术应用。研究包括培训学生以及通过谈判和出版物对结果进行广泛传播。此外，该研究可能对等离子体技术（例如，血浆加工，核融合）有影响，其中灰尘等离子体概念可以发挥作用。此外，某些研究可能与光子技术的局部研究领域重叠（例如光子晶体）。该提案已提交给NSF-DOE在等离子体科学与工程联合招标方面的NSF-DOE合作伙伴关系08-589。该奖项是由物理学部的血浆物理计划资助的。
