Journal ArticleDOI
Metamaterial-Inspired Model for Electron Waves in Bulk Semiconductors
TL;DR: In this article, an effective medium description for the propagation of electron matter waves in bulk semiconductors with a zinc-blende structure was developed based on an analogy with electromagnetic metamaterials.
Journal ArticleDOI
Probing polarization and dielectric function of molecules with higher order harmonics in scattering-near-field scanning optical microscopy
Maxim P. Nikiforov,Susanne C. Kehr,Tae Hong Park,Peter Milde,Ulrich Zerweck,Christian Loppacher,Lukas M. Eng,Michael J. Therien,Nader Engheta,Dawn A. Bonnell +9 more
TL;DR: In this article, the authors demonstrate the use of harmonics up to fourth order and the polarization dependence of incident light to probe dielectric properties on idealized samples of monolayers of organic molecules on atomically smooth substrates.
Journal ArticleDOI
Enhancement of radiation from dielectric waveguides using resonant plasmonic coreshells
TL;DR: In this article, a method for enhancing radiation from a dielectric waveguide through the use of resonant coreshells is presented, which act as a compact impedance matching element between the guided modes of the waveguide and radiation modes in free space.
Proceedings ArticleDOI
All-metallic epsilon-near-zero graded-index converging lens at terahertz frequencies
TL;DR: In this article, an all-metallic epsilon-near-zero graded-index lens is demonstrated working at terahertz (THz) frequencies using an array of narrow hollow rectangular waveguides.
Proceedings ArticleDOI
Nanocircuit elements, nano-transmission lines and nano-antennas using plasmonic materials in the optical domain
TL;DR: In this paper, a nano-transmission line with a lateral cross-section far less than the operating wavelength is described, analogous to the conventional transmission line in the microwave regime.
