Published in 2022 at "Optics express"

DOI: 10.1364/oe.476888

Abstract: We theoretically present the waveform controls of terahertz (THz) radiations generated from homogeneous and rippled plasma within inhomogeneous external electrostatic field. The Particle-in-cell (PIC) simulations is implemented to demonstrate generation and controllability of three types… read more here.

Published in 2018 at "PLoS ONE"

DOI: 10.1371/journal.pone.0201572

Abstract: On the basis of the Crank-Nicolson method, we develop a conservative finite-difference scheme for investigation of the THz pulse interaction with a multilevel medium, covered by a disordered layered structure, in the framework of the… read more here.
