    • Aharanov-Bohm effects induced by light in a fiber 

      Kulik, I. O.; Shumovsky, A. (A I P Publishing LLC, 1996-08-02)
      A weakly coupled normal-metal ring surrounding an optical fiber is considered under the condition that the frequency of light in fiber is larger than the conduction bandwidth of the metal. It is shown that in the presence ...
    • AlGaN/GaN HEMT-based fully monolithic X-band low noise amplifier 

      Schwindt, R.; Kumar, V.; Aktas, O.; Lee, J. W.; Adesida, I. (Wiley, 2005-04)
      A fully monolithic AlGaN/GaN HEMT-based low noise amplifier is reported. The circuit demonstrated a noise figure of 3.5 dB, gain of -7.5 dB, input return loss of -7.5 dB, and output return loss of -15 dB at 8.5 GHz. The ...
    • Bi-angular lens for material characterization 

      Yaralioglu G.G.; Atalar, Abdullah; Koymen H. (IEEE, Piscataway, NJ, United States, 1994)
      In this paper a new lens design is proposed for characterization of layered materials. Lamb wave lens employs Lamb waves for this purpose since these waves propagate along interfaces. However, below cut-off angle, the ...
    • Experimental study of linear closed-loop control of subsonic cavity flow 

      Yan P.; Debiasi, M.; Yuan X.; Little J.; Özbay H.; Samimy, M. (2006)
      A study is presented of the modeling and implementation of different concepts for linear feedback control of a single-mode resonance shallow cavity flow. When a physics-based linear model is used for cavity pressure ...
    • The Fractional Fourier transform and harmonic oscillation 

      Kutay, M. A.; Ozaktas, H. M. (Springer, 2002)
      The ath-order fractional Fourier transform is a generalization of the ordinary Fourier transform such that the zeroth-order fractional Fourier transform operation is equal to the identity operation and the first-order ...
    • On a problem of H.Shapiro 

      Ostrovskii, I.; Ulanovskii, A. (Elsevier, 2004-02)
      Let μ be a real measure on the line such that its Poisson integral M(z) converges and satisfies M(x+ iy) ≤ Ae-cyα, y → + ∞, for some constants A, c > 0 and 0 < α ≤ 1. We show that for 1/2 < α ≤ 1 the measure μ must have ...
    • Plane-wave dynamics of optical parametric oscillation with simultaneous sum-frequency generation 

      Dikmelik, Y.; Akgün, G.; Aytür, O. (Institute of Electrical and Electronics Engineers, 1999-06)
      This paper presents a theoretical analysis of sum-frequency generating optical parametric oscillators where a single nonlinear crystal is used for both parametric generation and sum-frequency generation. In these devices, ...
    • Plasma modes in layered superconductors 

      Askerzade, I. N.; Tanatar, B. (Elsevier B.V., 2005)
      An expression for the plasmon spectrum in the layered superconductors with arbitrary thickness of planes, which varies within a wide range is obtained. The obtained result can be attractive for the explanation of experimental ...
    • Plasmons and the drag effect in a strong magnetic field 

      Manolescu, A.; Tanatar, B. (Elsevier B.V., 2002)
      We study the effect of magnetoplasmons on the drag resistance in a strong magnetic field, at finite temperatures. The typical magnetic field is about 1 T, and the temperature is up to 10 K. The Landau levels are broadened ...
    • Simulation of millimeter-wave gunn oscillations in gallium nitride 

      Sevik, C.; Bulutay, C. (2004)
      High field transport in wide bandgap semiconductors like GaN is of great technological importance. The negative differential mobility regime at high fields, under suitable conditions, can lead to millimeterwave Gunn ...
    • Simultaneous non-contact atomic force microscopy (nc-AFM)/STM imaging and force spectroscopy of Si(1 0 0)(2 × 1) with small oscillation amplitudes 

      Özer, H. Ö.; Atabak, M.; Ellialtoğlu, R. M.; Oral, A. (Elsevier Science B.V., 2002)
      Si(1 0 0)(2 × 1) surface is imaged using a new non-contact atomic force microscopy (nc-AFM)/STM with sub-Ångström oscillation amplitudes using stiff tungsten levers. Simultaneous force gradient and STM images of individual ...
    • Vortex lattice of a Bose-Einstein condensate in a rotating anisotropic trap 

      Oktel, M. Ö. (American Physical Society, 2004)
      The behavior of Bose-Einstein condensates (BEC) with a vortex lattice in a rotating anisotropic trap was studied. The single-particle wave functions for a rotating anisotropy trap were found by exactly diagonalizing the ...
