Bow-Tie Antenna

By using aluminum and indium, it has become possible to obtain SERS enhancement in the DUV spectral region. Several types of aluminum nanostructures have been used, including rough films, nanoparticles, and bow-tie antennas. At present, however, only a few different molecules—mostly adenine— have been tested as samples for DUV-SERS. To push the development of DUV-SERS to the next... [Pg.154]

In this section the results of the previous two sections are combined to compare several NFT designs that have been suggested for use in data storage. In particular, the triangle antenna and the bow-tie antenna are compared with the circular aperture, the tapered rectangular aperture, the bow-tie aperture, and the C aperture. All NFTs are illuminated by a highly focused beam using a SIL with a refractive index of 1.5 to obtain an optical spot size with dimensions... [Pg.73]

An aperture in the shape of a bow tie, also called a bow-tie slot antenna is shown in Fig. 22. This aperture is essentially a rectangular aperture with a constriction in the center. When it is illuminated with light polarized across the gap as shown in the figure, a LSPR is excited which oscillates surface charge into the two tips in the center. The sharpened tips enhance the field strength in this region via the... [Pg.79]
