Superscattering, Superabsorption, and Nonreciprocity in Nonlinear Antennas
Lin Cheng, Rasoul Alaee, Akbar Safari +3
We propose tunable nonlinear antennas based on an epsilon-near-zero material with a large optical nonlinearity. We show that the absorption and scattering cross sections of the ant…
Enhanced Nonlinear Optical Responses of Layered Epsilon-Near-Zero Metamaterials at Visible Frequencies
Sisira Suresh, Orad Reshef, M. Zahirul Alam +3
Optical materials with vanishing dielectric permittivity, known as epsilon-near-zero (ENZ) materials, have been shown to possess enhanced nonlinear optical responses in their ENZ r…
Tunable THz absorption in photonic crystal including graphene and metamaterial
M. Montaseri, M. Hosseini, M. J. Karimi
In this paper, a photonic crystal containing graphene and metamaterial layers is investigated. The absorption spectrum of the structure in the terahertz range is obtained using the…
Optimization of terahertz absorption in periodic quantum well structures
Zahra Javidi, Mehdi Hosseini, Mohammad Javad Karimi
In this work, the linear absorption spectra for periodic arrays of GaAs-GaAsAl quantum wells with different thicknesses, inside electromagnetic wave has been studied. The eigen ene…
