“…If the transmission frequencies can be increased to THz/optical range then the corresponding antenna sizes decrease, occupying much less chip real estate. One possibility is to use nanoscale antennas based on CNTs operating in the THz/optical frequency range [51][52][53][54]. Bundles of CNTs are predicted to enhance performance of antenna modules by up to 40dB in radiation efficiency and provide excellent directional properties in far-field patterns [55].…”

“…While numerous experimental measurements of the optical spectra of CNTs have been reported over the year, it remains challenging to compute the scattered field from first principles, first because of the lack of exact knowledge of the geometry and structure at the nanoscale, and second since electromagnetic theory, usually successful at the computational level in the macroscopic scale, cannot be directly applied at the microscopic scale. Here, we provide a theoretical description of the electromagnetic scattering by both singleand multi -wall carbon nanotubes based on an effective-boundary condition derived previously using a phenomenological quantum model [8][9][10]. The analytical solution for the scattering problem developed by the authors for single-wall CNT in [11,12] was compared with experiments and good results had been obtained.…”

Abstract-We develop an efficient algorithm for the computation of the complete transmitted and reflected electromagnetic fields in generic 2D arrays of carbon nanotubes (CNTs). The method relies on first approaching individual CNTs using an effective-boundary condition based on a proper quantum conductivity model. An exact eigenmode solution is obtained for this problem for both single-wall and multi-wall CNTs, which then is integrated with Floquet mode theory to handle periodic arrays of CNTs. The algorithm's convergence rate is accelerated using special methods and then applied to the analysis and design of various multi-layered CNT-based photonic crystal devices. It is shown that the proposed method can clearly demarcate the intrinsic optical resonances due to electronic transitions in individual CNTS and new sets of "geometric" optical resonances produced by the array spatial structure. The algorithm can be used to analyze measured optical spectra of CNT composites and to design new nanomaterial-engineered optical bandgap devices.

“…The SWNT-based terahertz detectors have already been demonstrated experimentally [6,7]. Metallic SWNT antennas [8,9,10,11] can be utilized for the terazertz radiation manipulation as they are predicted to possess antenna resonances in the frequency rage [9]. In contrast, semiconducting SWNTs weakly interact with electromagnetic radiation in this frequency range and therefore are not suitable for terahertz applications.…”

Abstract. We demonstrate theoretically that the chemical modification of the bundles and composites containing mixture of semiconducting and metallic single-wall carbon nanotubes (SWNTs) leads to the substantial enhancement of the characteristics of their electromagnetic response in the terahertz (THz) frequency range. Boron and nitrogen doping is used to illustrate the effect. In particular, frequencies of antenna resonances in the bundles containing doped SWNTs are shifted to the blue in comparison to the ones in the bundles containing the same number of pristine SWNTs. Moreover, doping increases the resonant values of the bundles polarizability. Enhancement of the conductivity of the composite containing doped SWNTs is also demonstrated. The origin of the behavior is the metallization of the chemically modified semiconducting SWNTs in the bundles and composites due to the injection of the additional charge carriers.
