Thesis (Ph. D.)--University of Rochester. Institute of Optics, 2009.The recent trend in applications that rely on focal fields has been toward increasingly high-aperture systems, which cannot be described by the paraxial theory. This trend is related to desired increases in resolution, energy density or both, depending on the application in question. In this thesis, the upper bound on the focal energy density (irradiance) is found for both scalar and electromagnetic fields with any directional spread and given total power. The remainder of the thesis is devoted to efficient modeling of focused fields with directional spread too great to be modeled by paraxial fields, but with a distinct direction of propagation. New, efficient bases...
