We reanalyze a selection of the XMM-Newton RGS (Reflection Grating Spectrometer) data of two classical novae; V4743 Sgr and V2491 Cyg. The high resolution nova spectra in the X-ray wavelengths show existence of absorption features (e.g., blue shifted). Our main aim is to model the absorption components detected in the high resolution spectra independently from the assumed continuum model. We assume that there is complex absorption of interstellar, photospheric, and of collisionally and/or photoionized gas origin in the moving material along the line of sight from a nova wind or ejecta. In addition to deriving the absorption properties, we obtain CNO abundances of elements in the ejecta/nova wind.

Time-domain mapping of electromagnetic ray movement inside anisotropic spherical resonator
Biber, A; Golick, A; Tomak, Mehmet (2002-09-01)
This paper presents the analytical proof of "Time-Domain Mapping Method" for the spherical resonator made up of uniaxial crystal. In this way, the main types of caustics inside the spherical resonator made up of uniaxial crystal, which were investigated numerically before, are confirmed analytically. It is engraved that the problem of the ray flow inside the spherical resonator can be reduced to the problem of the ray flow inside metal cavity shaped as spheroid.
CCD photometry of V2275 Cygni (N Cyg 2001 No.2) in 2002-2003
Balman, Şölen; Yilmaz, A; Retter, A; Saygac, T; Esenoglu, H (2004-07-16)
We present the CCD photometry, light curve and time series analysis of the classical nova V2275 Cyg. The source is observed for 14 nights in total using standard R filters in 2002 and 2003 with the 1.5m Russian-Turkish joint telescope (RTT150) at the TUBITAK National Observatory (TUG) in Antalya Turkey. We report the detection of two periodicities in the light curve of the nova : a) P-1=0.31449(15) d, b) P-2=0.017079(17) d. We propose that the first period is the orbital period of the system as a result of ...
Apertureless scanning near field optical microscope with sub-10 nm resolution
Bek, Alpan; KERN, KLAUS (AIP Publishing, 2006-04-01)
We report on the implementation of a versatile dynamic mode apertureless scanning near field optical microscope (aSNOM) for nanoscopic investigations of optical properties at surfaces and interfaces. The newly developed modular aSNOM optomechanical unit is essentially integrable with a multitude of laser sources, homemade scanning probe microscopes (SPMs) as well as commercially available SPMs as demonstrated here. The instrument is especially designed to image opaque surfaces without a restriction to trans...
Efficient Computation of Green's Functions for Multilayer Media in the Context of 5G Applications
Mittra, Raj; Özgün, Özlem; Li, Chao; Kuzuoğlu, Mustafa (2021-03-22)
This paper presents a novel method for effective computation of Sommerfeld integrals which arise in problems involving antennas or scatterers embedded in planar multilayered media. Sommerfeld integrals that need to be computed in the evaluation of spatial-domain Green's functions are often highly oscillatory and slowly decaying. For this reason, standard numerical integration methods are not efficient for such integrals, especially at millimeter waves. The main motivation of the proposed method is to comput...
On-chip optical filters with designable characteristics based on an interferometer with embedded silicon photonic structures
Kocaman, Serdar; Panoiu, Nicolae C.; Lu, Ming; Wong, Chee Wei (2012-02-15)
We demonstrate chip-scale flat-top filters at near-IR wavelengths using negative index photonic crystal based MachZehnder interferometers. Supported by full three-dimensional numerical simulations, we experimentally demonstrate a new approach for engineering high-pass, low-pass, bandpass, and band-reject filters, based on designing the photonic band diagram both within the bandgap frequency region and away from it. We further show that our approach can be used to design filters that have tunable multilevel ...
