Abstract
Optical antennas are the short-wavelength equivalent of the common radiofrequency structures. Taking this analogy one step further, the design concepts of radiofrequency lumped circuit elements can effectively be transplanted to optical wavelengths.
The development of advanced optical structures has enabled tremendous levels of control over the propagation and manipulation of light waves. This control is used in many technological applications, including optical microscopy, solar cells and efficient solid-state light sources, and it has also become important in biotechnology, medicine and the modern-day telecommunications industry.
