光学纳米天线，特别是偶极子类型的光学纳米天线，已经被许多研究小组从理论和实验上证明。同样，等离子体波导管和光路也取得了重大进展。在无线电频率和微波中，一类被称为介质谐振器天线(DRA)的天线被设计用于多种应用，包括卫星和雷达系统，其辐射元件是介质谐振器(DR)。在这封信中，我们探索了设计纳米DRAS(NDRAS)的可能性和优势，即用于纳米光子学应用的DRAS。对光通信频谱的短频段(S频段)、常规频段(C频段)和长频段(L频段)进行了数值计算，给出了圆柱形NDRA型天线的基本参数。
Optical nanoantennas, especially of the dipole type, have been theoretically and experimentally demonstrated by many research groups. Likewise, the plasmonic waveguides and optical circuits have experienced significant advances. In radio frequencies and microwaves a category of antenna known as dielectric resonator antenna (DRA), whose radiant element is a dielectric resonator (DR), has been designed for several applications, including satellite and radar systems. In this letter, we explore the possibilities and advantages to design nano DRAs (NDRAs), i. e., DRAs for nanophotonics applications. Numerical demonstrations showing the fundamental antenna parameters for a circular cylindrical NDRA type have been carried out for the short (S), conventional (C), and long (L) bands of the optical communication spectrum.
