摘要

本文综述了近15年来纳米天线在红外波段和可见光波段的研究进展。本调查的目的是强调基于应用的基本见解和最新发展。此外，还介绍了表征和制备方法。作者还提出了一种多层几何结构的偶极子纳米天线，该天线具有更好的效率和更宽的带宽。其阻抗带宽为312太赫兹，最大辐射效率和峰值实现增益分别为82.1%和2.95 dBi。该天线提供全向辐射方向图，是能量收集和其他光子应用的合适候选者。

State-of-the-Art of Nanoantenna Designs in Infrared and Visible Regions: An Application-Oriented Review

This review article outlines research on nanoantennas in infrared bands and visible bands over the last one and half decades. The objective of this survey is to highlight basic insights and state-of-the-art developments based on applications. Besides, characterization and fabrication methods are also presented. The authors also proposed a dipole nanoantenna of multi-layer geometry which provides better efficiency and wider bandwidth. It offers an impedance bandwidth of 312 THz with maximum radiation efficiency and peak realized gain of 82.1% and 2.95 dBi, respectively. This proposed antenna provides an omnidirectional radiation pattern, which is a suitable candidate for energy harvesting and other photonic applications.
