Noble metals can support surface plasmons within and around the visible spectrum, which allows the surface plasmons to be excited by regular optical sources. However, the practical usability of surface plasmons is significantly reduced by the losses in metallic materials and the short propagating length. Methods of reducing such losses and increasing the propagating length are highly desirable.</p><p>In this thesis, surface plasmons are analyzed both theoretically and numerically. A composite material reducing surface plasmon losses and increasing the range of propagation is proposed.</p><p>In numerical modeling, absorbing boundary conditions for surface plasmons are proposed and tested; such conditions reduce the size of the computational domain and the computational resources required.</p> 2008-05-12 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1207712683 http://rave.ohiolink.edu/etdc/view?acc_num=akron1207712683 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
