An analytical approach to the design of multiple mode rectangular cavity waveguide filters
(Institute of Electrical and Electronics Engineers Inc., 2017)The multiple mode rectangular cavity structure with square corner cuts is revisited. An attempt to predict the physical dimensions of the cavity for dual mode second-order and triple mode third-order filters is made. ... -
Application of a mode-locked fiber laser for highly time resolved broadband absorption spectroscopy and laser-assisted breakdown on micro-plasmas
(IOP Publishing, 2012-05-29)Absorption spectroscopy is known to be a powerful tool to gain spatially and temporally resolved information on excited and reactive species in a plasma discharge. Furthermore, the interaction of the discharge with short ... -
Crossed chiral band approximation for wide-band self-collimation of light
(Institute of Physics Publishing, 2020)We propose a perspective to the evaluation of the wide bandwidth phenomenon for low-symmetric photonic structures, by introducing the band tailoring and chiral band approximation on the self-collimation effect. In the ... -
Dispersion irrelevant wideband asymmetric transmission in dielectric photonic crystal gratings
(Optical Society of America, 2012-11-22)Wideband suppression of zero order and relevant strongly asymmetric transmission can be obtained in photonic crystal gratings that are made of linear isotropic materials and show the broken structural (axial) symmetry, ... -
Dispersion of multi-walled carbon nanotubes in an aqueous medium by water-dispersible conjugated polymer nanoparticles
(2010)Vertically aligned multi-walled carbon nanotubes (MWCNTs) synthesized by the alcohol catalytic CVD (ACCVD) technique are dispersed in water with the aid of water-dispersible conjugated polymer nanoparticles (CPNs). The ... -
Dynamic correlation effects on the plasmon dispersion in a two-dimensional electron gas
(The American Physical Society, 2003)The charge-density oscillations (plasmons) of a low-density two-dimensional uniform electron gas are studied within the framework of finite temperature and frequency dependent (dynamic) version of Singwi, Tosi, Land, and ... -
Dynamic correlations in double-layer electron systems
(The American Physical Society, 2001)We study the effects of dynamic correlations on the ground-state properties of a double-layer two-dimensional electron gas within the quantum Singwi-Tosi-Land-Sjölander theory (STLS). The intralayer and interlayer static ... -
Improving the accuracy of a time lens
(Optical Society of America, 1997-11)A method for improving the accuracy of temporal imaging with an imperfect time lens is proposed. Signal distortion arising from complicated dispersion of the delay lines can be reduced considerably by appropriate choice ... -
Numerical study on the dispersion and deposition of particles in evaporating sessile droplets
(Bilkent University, 2022-09)Evaporating sessile droplets including dispersed particles are utilized in the coating, printing, and biomedical applications. Modeling this problem is a challenging process, therefore different assumptions are used in the ... -
Spatio-temporal evolution of ultrashort pulses in graded-index multimode fiber at normal dispersion
(IEEE, 2017)Summary form only given. A novel nonlinear phenomenon at normal dispersion regime inside of graded-index multimode fiber (GRIN MMF), geometric parametric instability (GPI), can be observed while propagating beam experiences ... -
Varentropy decreases under the polar transform
(Institute of Electrical and Electronics Engineers Inc., 2016)We consider the evolution of variance of entropy (varentropy) in the course of a polar transform operation on binary data elements (BDEs). A BDE is a pair (X,Y) consisting of a binary random variable X and an arbitrary ... -
Volume based texture mapping
(Bilkent University, 1995)'I'he most realistic and attractive computer generated images are usually those that contain a large arnount of visual complexity and detail. Texturing is a widely used way of adding visual complexity and detail to ...
