Array of dipoles near a hyperbolic metamaterial: Evanescent-to-propagating Floquet wave transformation
Caner Guclu, Salvatore Campione, Filippo Capolino
We investigate the capabilities of hyperbolic metamaterials (HMs) to couple near-fields (i.e., evanescent waves) emitted by a two-dimensional periodic array of electric dipoles to…
Theory of a Directive Optical Leaky Wave Antenna Integrated into a Resonator and Enhancement of Radiation Control
Caner Guclu, Salvatore Campione, Ozdal Boyraz +1
We provide for the first time the detailed study of the radiation performance of an optical leaky wave antenna (OLWA) integrated into a Fabry-Pérot resonator. We show that the radi…
Novel concept for pulse compression via structured spatial energy distribution
Venkata Ananth Tamma, Alexander Figotin, Filippo Capolino
We present a novel concept for pulse compression scheme applicable at RF, microwave and possibly to optical frequencies based on structured energy distribution in cavities supporti…
Second harmonic double resonance cones in dispersive hyperbolic metamaterials
Domenico de Ceglia, Maria Antonietta Vincenti, Salvatore Campione +3
We study the formation of second harmonic double-resonance cones in hyperbolic metamaterials. An electric dipole on the surface of the structure induces second harmonic light to pr…
Graphene-Dielectric Composite Metamaterials: Evolution from Elliptic to Hyperbolic Wavevector Dispersion and The Transverse Epsilon-Near-Zero Condition
Mohamed A. K. Othman, Caner Guclu, Filippo Capolino
We investigated a multilayer graphene-dielectric composite material, comprising graphene sheets separated by subwavelength-thick dielectric spacer, and found it to exhibit hyperbol…
Extension of Pierce model to multiple transmission lines interacting with an electron beam
Venkata Ananth Tamma, Filippo Capolino
A possible route towards achieving high power microwave (HPM) devices is through the use of novel slow-wave structures, represented by multiple coupled transmission lines (MTLs), a…
Low-damping epsilon-near-zero slabs: nonlinear and nonlocal optical properties
Domenico de Ceglia, Salvatore Campione, Maria Antonietta Vincenti +2
We investigate second harmonic generation, low-threshold multistability, all-optical switching, and inherently nonlocal effects due to the free-electron gas pressure in an epsilon-…
Thermal Hyperbolic Metamaterials
Yu Guo, Zubin Jacob
We explore the near-field radiative thermal energy transfer properties of hyperbolic metamaterials. The presence of unique electromagnetic states in a broad bandwidth leads to supe…
