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…

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…
