Real frequency design of multiband matching networks with mixed lumped-distributed elements and foster resonance sections
(IEEE, 2018)
In this study, a multiband matching network design technique is presented. Mixed lumped and distributed elements are used to form Transducer Power Gain (TPG) of the matching network. Finite frequency transmission zeros are ...
A numerical approach for the design of matching networks consisting of brune sections based on fujisawa constraints
(IEEE, 2018)
In this study, the realization problem of matching network consisting of Brune sections is investigated. In the synthesis of a general impedance function with finite transmission zeros, each transmission zero extraction ...
Dual band filter design for GSM bands using frequency mapping and real frequency technique
(IEEE, 2018)
In this study, dual band frequency mapping is incorporated with Real Frequency Technique to design a dual band filter for GSM900 and GSM1800/UMTS bands. The proposed real frequency design technique (RFT) involves a parametric ...
DAG 4m telescope: assembly, integration and testing
(SPIE-Int Soc Optical Engineering, 2018-07-06)
AMOS with EIE as a main subcontractor, was awarded a contract in November 2014 for the design, manufacturing and installation of a 4m-class telescope for the Turkish Eastern Anatolia Observatory (DAG) situated at 3170 m ...
Project management and status update for DAG (Eastern Anatolia Observatory) the 4 meter VIS/IR optical telescope
(SPIE-Int Soc Optical Engineering, 2018)
The new 4 m Turkish telescope, DAG (East Anatolian Observatory, Fig. 2), will be located on the summit of the mountain Konakli-Karakaya, at an altitude of 3170 m, near the city of Erzurum, Turkey. First light is expected ...
DAG-TGI: Turbulence generator instrument for DAG (Eastern Anatolia Observatory)
(SPIE-Int Soc Optical Engineering, 2018-07-18)
DAG (East Anatolia Observatory) Telescope has 4 m mirror with active optics (a0) and adaptive optics (AO) systems. In order to evaluate DAG's focal plane instruments and their installation, calibration and laboratory ...
In Flange Derotator Design for the 4m DAG telescope
(SPIE-INT Soc Optical Engineering, 2018-07-06)
The field rotation effect can be described as observing the gyration of an object with the pupil of the Eastern Anatolian Observatory (DAG) telescope around the optical axis under the influence of the latitude of the ...
Coordination in building an observatory: A case study of Eastern Anatolian Observatory (DAG)
(SPIE-Int Soc Optical Engineering, 2018)
Eastern Anatolian Observatory (DAG) is designed to build on one of the summits of Palandoken Mountains in Erzurum, Turkey, at an altitude of 3,151 meters. The building is under construction since 2015 and expected to be ...
Production of M1, M2 and M3 mirrors for DAG project (Belgium, Russia). Current status
(SPIE-Int Soc Optical Engineering, 2018)
This paper describes the technology of production and testing of mirrors for DAG Telescope (Doge Anadolu Gozlemevi) produced by Belgium Company AMOS. JSC LZOS fulfils works on production and testing of three mirrors: primary ...
A flexible adaptive optics concept for general purpose high angular resolution science on the DAG 4m telescope
(SPIE-Int Soc Optical Engineering, 2018)
Thanks to the availability of high actuator density deformable mirrors (ALPAO 468 DM), the high versatility of the pyramid wavefront sensor and above all, the venue of essentially no noise EMCCD detectors, it becomes ...
