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 ...
A new method and computer-controlled system for measuring the time constant of real thermoelectric modules
(2012)
Thermoelectric and dynamic parameters of thermoelectric (TE) modules such as time constant are of crucial importance in production and utilization of these modules. Many techniques, apparatuses and software have been ...
Computer controlled test system for measuring the parameters of the real thermoelectric module
(Elsevier Ltd, 2011)
Different methods have been developed for measuring the performances of thermoelectric (TE) modules. However, the foundation of these methods accepts the parameters of semiconductors as constant and foresees temperature ...
Application of iOS/Android based assessment and monitoring system for building inventory under seismic impact
(Union of Croatian Civil Engineers and Technicians, 2018)
The possibility of creating an "ID card" for each new and existing building in urban areas, based on transfer of necessary data into electronic format, is analysed in the paper. Local governments, public institutions, ...
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 ...
Microcontroller-based test system for determining the P-N type and Seebeck coefficient of the thermoelectric semiconductors
(Elsevier B.V., 2019)
In this study, a microcontroller-based test system is designed and realized to determine the Seebeck coefficient (alpha) and electrical conductivity type of thermoelectric (TE) semiconductors. The test system uses Hot-Probe ...
The homogeneity map method for speckle reduction in diagnostic ultrasound images
(Elsevier B.V., 2015)
This paper proposes a new method to reduce speckle noise in diagnostic ultrasound images by improving the speckle reduction capacity of an edge-sensitive filter. A homogeneity map is generated according to the local ...
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 ...
