Photonic band gap structures for WDM applications
A new structure by combining a single cavity and coupled-cavity waveguides (CCWs) for wavelength division multiplexing (WDM) applications was proposed. As such, a structure in which the coupling between the cavity mode and ...
Stagger tuned cMUT array for wideband airborne applications
In this study, we explore the limits of cMUTs in air-borne applications. First we investigate the ways of increasing the bandwidth of a single cMUT cell in air. The effect of array operation is also considered in order to ...
Remarks on H ∞ controller design for SISO plants with time delays
The skew Toeplitz approach is one of the well developed methods to design H ∞ controllers for infinite dimensional systems. In order to be able to use this method the plant needs to be factorized in some special manner. ...
Bandwidth improvement in a cMUT array with mixed sized elements
A capacitive micromachined ultrasonic transducer (cMUT) is typically fabricated by concatenation of several cMUT cells with identical physical dimensions. If the membrane thickness is kept fixed, the radius of the cMUT ...

Plant Order Reduction for Controller Design
Two dual methods of plant order reduction for controller design are proposed for linear, time-invariant, multi-input multi-output systems. The model reduction methods are tailored towards closed-loop stability and performance ...
Large flat plate models in the physical optics method for RCS calculations
The calculation of Radar Cross Section (RCS) of arbitrarily large perfectly conducting body is presented. The body is modelled as triangular meshes of any size by the help of graphical tools. For the calculation of scattered ...
Systematic evaluation of face detection algorithms on news videos [Yüz bulma yöntemlerinin haber videolari i̇çin sistematik karşilaştirilmasi]
People are the most important subjects in news videos and for proper retrieval of people images; face detection is a very crucial step. However, face detection and recognition in news videos is a very challenging task due ...
Vortex lattice of a Bose-Einstein condensate in a rotating anisotropic trap
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 ...
