摘要：
A directive radiation element, tapered dielectric nanorod antenna, fed by a metal-insulator-metal waveguide is studied at optical wavelengths. The characteristics are numerically investigated with the frequency-dependent FDTD method. The tapered nanorod achieves a higher actual gain than that with a nanodipole, with a low reflectivity of 0.07 being retained.
