Ring focus dual reflectors are the most modern forms of the dual reflectors. They have distinctive geometries which eliminate the aperture blocking that results from the mechanical structure of sub-reflector. This characteristic of ring focus dual reflectors provides a more controllable reflector pattern as compared with classical dual reflectors. Also, the shape of the reflector pattern is different from the classical dual reflectors because of the fact that ring focus dual reflector geometries are different from the geometries of classical dual reflectors. The main aim of this thesis is investigation of the advantages and disadvantages which are coming with the usage of ring focus dual reflectors. In accordance with this aim, the analytical methods which provide the calculation of reflector patterns will be examined and they will be applied to classical and ring focus dual reflectors. The novelties that ring focus dual reflectors bring about will be presented in the thesis and compatibility of the obtained results with the real world will be discussed.

Analytical Fresnel imaging models for photon sieves
Öktem, Sevinç Figen; Davila, Joseph M. (The Optical Society, 2018-11-21)
Photon sieves are a fairly new class of diffractive lenses that open unprecedented possibilities for high resolution imaging and spectroscopy, especially at short wavelengths such as UV and x-rays. In this paper, we model and analyze the image formation process of photon sieves using Fourier optics. We derive closed-form Fresnel imaging models that relate an input object to the image formed by a photon sieve system, both for coherent and incoherent illumination. These analytical models also provide a closed...
Evaluation of a 6 pole axial flux PM motor for Control Moment Gyroscope Application
Zeinali, Raza; Ertan, Hulusi Bülent (2015-09-04)
In a previous study a compact Control Moment Gyroscope (GMC) design, based on a 6-pole, axial flux (AF) motor was presented. The GMC design in that proposal was based on analytical expressions and naturally 3-D structure of the AF motor could not be fully taken into account. In this paper the designed motor is simulated using 3-D FEM solutions. The parameters of the design such as electric loading and current loading as well as the performance of the design such as phase current and the torque produced at 1...
Analysis of Conformal Frequency Selective Surface Radome
Dalkilic, Akin; Alatan, Lale; Top, Can Baris (2014-04-11)
In this paper, the transmission characteristics of a conformal frequency selective surface (FSS) radome which is designed to operate in Ku-band is compared to its planar counterpart. The radome is designed to have narrow band-pass characteristics with a performance that is independent of the polarization and the angle of incidence of the incoming wave. The optimum dimension of the radome is optimized through the simulations of the infinite planar structure. Then, the performance of the conformal structure i...
Analysis of narcissus effect in infrared optical systems with cooled detectors
Aslan, Serhat Hasan; Yerli, Sinan Kaan; Department of Physics (2022-7)
Infrared lens design has many aspects similar to visible lens design. Optical aberration types and calculations, tolerancing procedures are applied in the same way in infrared lens design as in the visible lens design. However, there are many design aspects in infrared lens which are very different from visible lens design. One of these aspects is the narcissus effect in infrared lenses utilizing cooled infrared detectors. Narcissus effect is a very well known phenomenon in infrared lens with cooled detecto...
Free Vibrations of Composite Plates Stiffened by Two Adhesively Bonded Plate Strips
Javanshir, Jaber; Farsadi, Touraj; Yuceoglu, Umur (2012-07-01)
In this study, the free flexural (or bending) vibration response of composite base-plate or panel systems stiffened by two adhesively bonded plate strips are theoretically analyzed in detail and numerically solved in terms of the mode shapes with their natural frequencies. Additionally, some important parametric studies are also included in the present study. The aforementioned bonded and stiffened system is composed of an orthotropic Mindlin base plate or panel stiffened or reinforced by the dissimilar, or...
