      New high-resolution display device for holographic three-dimensional video: principles and simulations 

      Onural, L.; Bozdağı, G.; Atalar, Abdullah (SPIE, 1994)
      A new acousto-optical holographic display device, which is expected to solve the display resolution and refresh problems that are common to available holographic displays, is proposed. The device is based on the ...

      Independent parallel lithography using the atomic force microscope 

      Minne, S. C.; Manalis, S. R.; Atalar, Abdullah; Quate, C. F. (A I P Publishing LLC, 1996-05)
      Independent parallel features have been lithographically patterned with a 2×1 array of individually controlled cantilevers using an atomic force microscope. Control of the individual cantilevers was achieved with an ...

      High‐speed atomic force microscopy using an integrated actuator and optical lever detection 

      Manalis, S. R.; Minne, S. C.; Atalar, Abdullah; Quate, C. F. (A I P Publishing LLC, 1996-09)
      A new procedure for high‐speed imaging with the atomic force microscope that combines an integrated ZnO piezoelectric actuator with an optical lever sensor has yielded an imaging bandwidth of 33 kHz. This bandwidth is ...

      Parallel atomic force microscopy with optical interferometric detection 

      Sulchek, T.; Grow, R. J.; Yaralioglu, G. G.; Minne, S. C.; Quate, C. F.; Manalis, S. R.; Kiraz, A.; Aydine, A.; Atalar, Abdullah (American Institute of Physics, 2001-01-05)
      We have developed an atomic force microscope that uses interferometry for parallel readout of a cantilever array. Each cantilever contains a phase sensitive diffraction grating consisting of a reference and movable set of ...

      An analytical approach to the design of multiple mode rectangular cavity waveguide filters 

      Kelleci, C.; Atalar, Abdullah (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. ...

      Centimeter scale atomic force microscope imaging and lithography 

      Minne, S. C.; Adams, J. D.; Yaralioglu, G.; Manalis, S. R.; Atalar, Abdullah; Quate, C. F. (A I P Publishing LLC, 1998-09-21)
      We present a 4 mm2 image taken with a parallel array of 10 cantilevers, an image spanning 6.4 mm taken with 32 cantilevers, and lithography over a 100 mm2 area using an array of 50 cantilevers. All of these results represent ...

      Bilateral CMUT cells and arrays: equivalent circuits, diffraction constants, and substrate impedance 

      Köymen, Hayrettin; Atalar, Abdullah; Taşdelen, A. S. (Institute of Electrical and Electronics Engineers Inc., 2017)
      We introduce the large-signal and small-signal equivalent circuit models for a capacitive micromachined ultrasonic transducer (CMUT) cell, which has radiating plates on both sides. We present the diffraction coefficient ...

      Noise figure degradation in balanced amplifiers 

      Coskun, A. A.; Atalar, Abdullah (Institute of Electrical and Electronics Engineers Inc., 2017)
      Balanced amplifiers suffer from the noise figure performance in comparison with a stand-alone amplifier even with an ideal input divider. The noise parameters degrade further with an imperfect divider. We present exact and ...

      Contact imaging in the atomic force microscope using a higher order flexural mode combined with a new sensor 

      Minne, S. C.; Manalis, S. R.; Atalar, Abdullah; Quate, C. F. (A I P Publishing LLC, 1996-01)
      Using an atomic force microscope (AFM) with a silicon cantilever partially covered with a layer of zinc oxide (ZnO), we have imaged in the constant force mode by employing the ZnO as both a sensor and actuator. The cantilever ...

      Theory and analysis of electrode size optimization for capacitive microfabricated ultrasonic transducers 

      Bozkurt, A.; Ladabaum, I.; Atalar, Abdullah; Khuri-Yakub, B. T. (Institute of Electrical and Electronics Engineers, 1999-11)
      Theoretical analysis and computer simulations of capacitive microfabricated ultrasonic transducers indicate that device performance can be optimized through judicious patterning of electrodes. The conceptual basis of the ...
