By applying the optical nanocircuit concepts to metasurfaces, we propose an effective route to locally control light transmission over a deeply subwavelength scale. This concept realizes the optical equivalent of a transmit-array, whose use is demonstrated for light bending and focusing with unprecedented efficiency over a subwavelength distance, with crucial benefits for nano-optics applications. These findings may lead to large improvements in the manipulation of optical transmission and…

The development of new materials for low-loss MM components and telecommunication devices is required because metals have traditionally been the material of choice for the building blocks, but they suffer from high resistive losses.

Circuit elements at optical frequencies: nanoinductors, nanocapacitors, and nanoresistors.

Three basic circuit elements, i.e., nanoinductors, nanocapacitors, and nanoresistors, are discussed in terms of small nanostructures with different material properties, which may provide road maps for the synthesis of more complex circuits in the IR and visible bands.
