An antenna array that is metres high and wide can detect and transmit radio waves. This effect has now been demonstrated at much smaller electromagnetic wavelengths in a nanoscale array of carbon nanotubes. 
Carbon Nanotubes as Optical Antennae
Light scattering from an array of aligned multiwall carbon nanotubes (MWCNTs) has previously been investigated, and shown to be consistent with that from an array of antennae. Two basic antenna

In this paper electromagnetic properties of periodic arrays of single-wall metallic carbon nanotubes (CNs) are presented. Semiclassical model, based on periodic Green's function, which takes into
Thermal radiation from carbon nanotubes in the terahertz range.
The thermal radiation from an isolated finite-length carbon nanotube (CNT) is theoretically investigated both in near- and far-field zones and the concept of a CNT as a thermal nanoantenna is proposed.
Optical Response of Finite-Length Carbon Nanotubes
Optical response of finite-length metallic carbon nanotubes is calculated including effects of induced edge charges in a self-consistent manner. The results show that the main resonance corresponding
Surface plasmons localization on field emitters arrays for microwave modulation of tunneling currents
We present the first steps for the validation of the concept of a new optically driven field emission cathode. The approach relies on the interaction of surface plasmons with vertically aligned
Nanoscale fluorescence microscopy using carbon nanotubes
We demonstrate the use of single-walled carbon nanotubes as nano-optical probes in apertureless near-field fluorescence microscopy. The carbon nanotubes strongly quench fluorescence leading to
Interaction of electromagnetic radiation in the 20–200 GHz frequency range with arrays of carbon nanotubes with ferromagnetic nanoparticles
It is shown that the influence of the resonant circuits leads to the emergence of specific resonances, namely peaks and valleys in the frequency dependence of the permeability of the nanocomposite, and in the frequencies of the reflection and transmission of electromagnetic radiation.
Characterization of the radiation from single-walled zig-zag carbon nanotubes at terahertz range
This paper investigates the radiation characteristics of metal single-walled zig-zag carbon nanotubes as a dipole antenna at terahertz wave range. The current distribution, input impedance and mutual


Receiving and transmitting light-like radio waves: Antenna effect in arrays of aligned carbon nanotubes
We present optical measurements of random arrays of aligned carbon nanotubes, and show that the response is consistent with conventional radio antenna theory. We first demonstrate the polarization
Phonons in carbon nanotubes
A broad review of the unusual one-dimensional properties of phonons in carbon nanotubes is presented, including phonons in isolated nanotubes and in crystalline arrays of nanotubes in nanotube
Polarized raman spectroscopy on isolated single-wall carbon nanotubes.
Orientation-dependent measurements reveal maximum intensity of all Raman modes when the nanotubes are aligned parallel to the polarization of the incident laser light, which deviates from the selection rules predicted by theoretical studies.
Polarized resonant Raman study of isolated single-wall carbon nanotubes: Symmetry selection rules, dipolar and multipolar antenna effects
We studied the polarization dependence of the resonance Raman spectra for several different isolated single-wall carbon nanotubes (SWNTs). One isolated SWNT acts as a dipolar antenna, polarized along
Interband optical transitions in left- and right-handed single-wall carbon nanotubes
The nanotube handedness is defined for the complete determination of the nanotube atomic structure by its diameter and chirality. The interband electronic optical transition matrix elements are

Polarized Raman spectra of high purity aligned arrays of multiwalled carbon nanotubes, prepared on silica substrates from the thermal decomposition of a ferrocene-xylene mixture, show a strong
