2018年7月19日 · We evaluate the use of optical nanoplasmonic antennas for the optical detection of mRNA in living cells and for in vivo molecular imaging. We also discuss nanoplasmonic optical antennas for...

Plasmonic nanoantennas can provide enhanced and controllable light-matter interactions and strong coupling between far-field radiation and localized sources at the nanoscale.

2012年10月15日 · We use the single plasmonic structures on top of the waveguide as dipolar building blocks for new types of antennas where the waveguide enhances the coupling between antenna elements. We report on waveguide hybridized Yagi–Uda antennas which show directionality in out-coupling of guided modes as well as directionality for in-coupling into the ...

2014年1月1日 · Plasmonic nanoantennas allow the efficient conversion of impinging optical radiation from the far-field into confined, strongly enhanced fields at the nanoscale or, by reciprocity, the coupling of localized optical sources to far-field radiation.

2014年12月1日 · Here, we review some of the recent advances in exploiting the potential of plasmonic antennas to realize robust nonlinear applications. Surface plasmon polaritons (SPPs) refer to the oscillation of charge density waves resonantly coupled to the electromagnetic field at a metal–dielectric interface [1].

2023年12月5日 · This article presents a systematic technique for designing a novel multiband plasmonic antenna based on graphene with a silicon nitride (SiO 3 N 4) dielectric substrate in the terahertz band frequencies. Higher conductivity values are found in the 1–5 THz ranges when the graphene conductivity values are measured at these band frequencies.

2023年9月12日 · Plasmonic modulator antennas have been recently shown to be able to efficiently upmix millimeter and THz waves onto optical frequencies. In this article, we introduce a theory and equivalent circuit models for designing and optimizing plasmonic modulator antennas.

Abstract— We explore the electromagnetic properties of nanostructured plasmonic antennas and show that they can be effectively used for light nano-confinement, field enhancement, and allow one to achieve left-handed response from the nanoantenna composite. properties of nanostructured composites.

In this review, we discuss fundamental characteristics of active PNAs and summarize recent progress in this burgeoning and challenging subfield of nano-optics.
