Thin wideband infrared metamaterial absorber with coplanar metallic patches of different sizes
(Institute of Electrical and Electronics Engineers Inc., 2016)
Infrared absorber concept is a vibrant research topic because of the importance of real world applications such as infrared detectors, thermal coolers and energy harvesters. In this paper, we propose and numerically analyze ...
Modified ultrasound despeckling assessment index for the Field II simulated cyst image
(Institution of Engineering and Technology, 2017)
Various methods have been proposed to reduce speckle noise, which decreases image quality in ultrasound images. The Field II simulated cyst image consists of three classes and is used to compare a proposed despeckle filter ...
Large bandwidth mode order converter by differential waveguides
(Optical Society of American (OSA), 2015)
In this article, we propose a large bandwidth mode-order converter design by dielectric waveguides with equal lengths but different cross-sectional areas. The efficient conversion between even and odd modes is verified by ...

In this study, a training set consisting of servo motors is designed to assist development of the students, especially who are in electrical, electronics and mechanical engineering, in industrial field. For this training ...
Wideband long wave infrared metamaterial absorbers based on silicon nitride
(American Institute of Physics Inc., 2016)
In this paper, we present silicon nitride metamaterial absorber designs that accomplish large bandwidth and high absorption in the long wave infrared (LWIR) region. These designs are based on the metal-insulator-metal ...
Analysis of analytical capacity for Fisher-Snedecor F fading channels with different transmission schemes
(Institution of Engineering and Technology, 2019)
This Letter presents capacity analysis of Fisher-Snedecor F fading channels under different transmission strategies. To this end, novel analytical expressions are proposed for optimal rate adaptation with constant transmit ...
Broadband LWIR and MWIR metamaterial absorbers with a simple design topology: Almost perfect absorption and super-octave band operation in MWIR band
(OSA - The Optical Society, 2017)
Infrared absorbers are essential structures in the design of thermal emitters and thermal infrared imagers. In this study, we propose simple topologies of wideband metamaterial absorbers operating in the long-wave infrared ...
Ultra-broadband long-wavelength infrared metamaterial absorber based on a double-layer metasurface structure
(OSA - The Optical Society, 2017)
In this paper, we report a metamaterial absorber design that achieves a broad absorption band encompassing the whole long-wavelength infrared (LWIR) region. The structure consists of two parallel metasurfaces buried in an ...
Efficient and broadband guided wave one-way mode-order conversion with theoretical and numerical analysis
(Optical Society of American (OSA), 2013)
In this article, an efficient method of asymmetric conversion of guided modes is investigated. From a basic excitation consisting of (mainly) the lowest-order mode of the input multimode strip waveguide, we achieve a ...
