Propagation of ionizing short laser pulses in a nonlinear optical medium
Deveci, Atalay; Yedierler, Burak; Department of Physics (2021-2-15)
Using a pseudo-spectral method that is split step Fourier method, obtaining a solutionfor propagation of ionizing short Gaussian pulse would be computationally inexpen-sive and practical. For a solution obtained by using ...
Fano control of plasmonic double-resonant systems
Postacı, Selen; Bek, Alpan; Taşgın, Mehmet Emre; Department of Physics (2021-2-12)
The nonlinear response of plasmonic nanostructures can be enhanced as a result of the localization of the incident field into nm-size regions, called hot spots. The Raman signal of a molecule can be enhanced by adsorbing i...
Numerical investigation of dbd in neon:effect of fluid modelling approaches
Somay, Mehmet Hilmi; Rafatov, İsmail; Department of Physics (2021-2-11)
The study deals with numerical modelling of dielectric barrier discharge (DBD) in Neon gas. The DBD models are based on the drift-diffusion theory of gas discharges. Two different approaches, namely, the so called simple a...
Investigation of the incommensurate (INC) phase between α and β phases in quartz and related materials
Ateş, Simge; Yurtseven, Hasan Hamit; Department of Physics (2021-2-10)
