Abstract:
An electromagnetically, responsive element includes an arrangement of controllable self-resonant bodies, such as atoms or quantum dots that form an effective dielectric constant, typically at or near a resonance.
Abstract:
An apparatus for enhanced transmission of radiation, comprising at least one radiation source (12), a metal plate (18) with a first (20) and a second (22) surface and at least one aperture (24) provided in the metal plate (18) and extending from the first (20) to the second (22) surface, the metal plate (18) having a periodic surface topography (26) provided on at least one of the first (20) and the second (22) surfaces, and radiation (13) coming from the radiation source (12) and being incident on one of the surfaces (20,22) of the metal plate (18) interacts with a surface plasmon mode on at least one of the surfaces of the metal plate (18), thereby enhancing transmission of radiation through the at least one aperture (24) of the metal plate (18). The apparatus for enhanced optical transmission comprises means (15) for generating radially polarized radiation (16), which is incident on one of the surfaces (20,22) of the metal plate (18) with a surface topography (26), resulting in a more efficient coupling of the radiation to the plasmons and thereby in a further enhancement of the optical transmission.
Abstract:
A variable hand placement sports equipment handle, such as a lacrosse stick handle, hockey stick handle, or field hockey stick handle, that includes a shaft (106) and at least one overlay (116, 114) attached to the shaft at a location of frequent hand placement. The overlays are specially located and structured to provide the shaft with structural and tactile features that correspond to and accommodate the way in which a player moves his hands along the shaft and grips the shaft. The structural and tactile features, such as ribs, grooves, and hourglass and conical shapes, are located on the shaft (106) to enhance a player's control of the shaft when performing various skills.
