Short planar glow discharges coupled to a resistive layer exhibit a wealth of spontaneous spatiotemporal patterns. Due to similarities with other pattern forming systems that are described by reaction-diffusion models, several authors have tried to derive such models from discharge physics. We investigate the temporal oscillations of the discharge system and find a cascade of period doubling events. This shows that the inner structure of the discharge is more complex than can be described by a two-component reaction-diffusion-model with negative differential conductivity. We also derive an alternative reduced model.

Oscillations in dc driven barrier discharges: Numerical solutions, stability analysis, and phase diagram SIJACIC, DD; EBERT, U; Rafatov, İsmail (American Physical Society (APS), 2005-06-01) A short gas-discharge layer sandwiched with a semiconductor layer between planar electrodes shows a variety of spatiotemporal patterns. We focus on the spontaneous temporal oscillations that occur while a dc voltage is applied and while the system stays spatially homogeneous; the results for these oscillations apply equally to a planar discharge in series with any resistor with capacitance. We define the minimal model, identify its independent dimensionless parameters, and then present the results of the fu...
Spatiotemporal patterns in a dc semiconductor-gas-discharge system: Stability analysis and full numerical solutions Rafatov, İsmail; EBERT, Ute (American Physical Society (APS), 2007-09-01) A system very similar to a dielectric barrier discharge, but with a simple stationary dc voltage, can be realized by sandwiching a gas discharge and a high-ohmic semiconductor layer between two planar electrodes. In experiments this system forms spatiotemporal and temporal patterns spontaneously, quite similarly to, e.g., Rayleigh-Benard convection. Here it is modeled with a simple discharge model with space charge effects, and the semiconductor is approximated as a linear conductor. In previous work, this ...
Multi-band polarization independent cylindrical metamaterial absorber and sensor application Dincer, Furkan; KARAASLAN, MUHARREM; Colak, Sule; TETİK, ERKAN; AKGÖL, OĞUZHAN; ALTINTAŞ, OLCAY; Sabah, Cumali (World Scientific Pub Co Pte Lt, 2016-03-30) A multi-band perfect metamaterial absorber (MA) based on a cylindrical waveguide with polarization independency is numerically presented and investigated in detail. The proposed absorber has a very simple configuration, and it operates at flexible frequency ranges within the microwave frequency regime by simply tuning the dimensions of the structure. The maximum absorption values are obtained as 99.9%, 97.5%, 85.8%, 68.2% and 40.2% at the frequencies of 1.34 GHz, 2.15 GHz, 3.2 GHz, 4.31 GHz and 5.41 GHz, re...
TEMPERATURE DEPENDENCE OF THE RAMAN FREQUENCIES IN THE gamma AND beta PHASES OF SOLID NITROGEN Yurtseven, Hasan Hamit (World Scientific Pub Co Pte Lt, 2010-12-20) We study here the Raman frequencies of the lattice modes (gamma and beta phases) and of an internal mode (gamma phase) as a function of temperature in solid nitrogen. The frequency shift, derived from the anharmonic self energy, is fitted to the experimental data for the Raman frequencies of the modes considered here in the gamma and beta phases of solid nitrogen.
Thermodynamics of Bose-Einstein gas trapped in D-dimensional quartic potentials Karabulut, Elife Oe; Koyuncu, Mustafa; Tomak, Mehmet (Elsevier BV, 2010-04-01) Quartic potentials play air important role in a broad range of fields in the Bose-Einstein Condensation (BEC) literature, from optical lattices to vortices and even to the quantum phase transitions. This also makes the study of thermodynamic properties of systems confined by these potentials interesting. For this purpose, the BEC of an ideal Bose system with a finite number of particles is considered in three and lower dimensions. A comprehensive thermodynamic analysis including the condensation temperature...
