Induced scattering of short radio pulses

, 2008
Effect of the induced Compton and Raman scattering on short, bright radio pulses is investigated. It is shown that when a single pulse propagates through the scattering medium, the effective optical depth is determined by the duration of the pulse but ...

Theoretical study of a multichannel plasmonic waveguide notch filter with double-sided nanodisk and two slot cavities

Results in Physics, 2019
Based on the transmission characteristics of surface plasmonic subwavelength structure, a multichannel plasmonic notch filter comprising two slot resonators and a nano-disk cavity with the metal-insulator-metal waveguide is proposed and investigated ...

Magnetically-tunable cutoff in asymmetric thin metal film plasmonic waveguide

, 2017
We theoretically investigated the magnetically-tunable cutoff of long-range surface plasmon polariton along thin metal film surrounded by a magneto-optic material on one side and by a nonmagnetic dielectric on the other side.

High-sensing properties of magnetic plasmon resonances in double- and triple-rod structures

, 2011
We numerically investigated the magnetic plasmon resonances in double-rod and triple-rod structures (DRSs and TRSs, respectively) for sensing applications. According to the equivalent circuit model, one magnetic plasmon mode was induced in the DRS.

Plasmon-induced transparency in twisted Fano terahertz metamaterials

Optical Materials Express, 2011
We investigate the effect of tweaking the quality (Q) factor of split ring resonators in a coupled state, giving rise to plasmonic induced transparency (PIT) which has two distinct, individually engineered resonance modes. The Q factor and the amplitude of each resonance are tuned by twisting them mutually in the unit cell consisting of a subradiant ...

Plasmon induced transparency and waveguide mode based optical biosensor for self-referencing sensing

Sensors International
In this paper, we present and investigate a novel approach for self-referenced sensing using a multilayer structure in Kretschmann configuration. The obtained results show that the structure can support two modes, plasmon-induced transparency and ...

Multiple Plasmon-Induced Transparency Responses in a Subwavelength Inclined Ring Resonators System

IEEE Photonics Journal, 2015
On the basis of single metal-insulator-metal (MIM) ring resonator (RR) structure, which acts as a band-stopped filter, a dual RR (DRR) system is proposed to obtain the plasmon-induced transparency (PIT) effect.

Plasmonic biosensor based on excellently absorbable adjustable plasmon-induced transparency in black phosphorus and graphene metamaterials

New Journal of Physics, 2020
Both black phosphorus (BP) and graphene metamaterials support surface plasmon resonance that is very sensitive to the local change of dielectric properties in the system.
